+\new{Reproducibility is defined as ``obtaining consistent results using the same input data; computational steps, methods, and code; and conditions of analysis'' \cite{fineberg19}.
+ Longevity is defined as the time that a project can be usable.
+ Usability is defined by context: for machines (machine-actionable, or executable files) \emph{and} humans (readability of the source).
+ Because many usage contexts don't involve execution; for example checking the configuration parameter of a single step of the analysis to re-\emph{use} in another project, or checking the version of used software, or source of the input data (extracting these from the outputs of execution is not always possible).}

+Longevity is as important in science as in some fields of industry, but not all; e.g., fast-evolving tools can be appropriate in short-term commercial projects.
+To highlight the necessity, a short review of commonly-used tools is provided below:
+(1) environment isolators (virtual machines, VMs, or containers);
+(2) package managers (PMs, like Conda, Nix, or Spack);
+(3) job management (like shell scripts or Make);
+(4) notebooks (like Jupyter).
+\new{For a much more comprehensive review of existing tools and solutions is available in the appendices.}
To isolate the environment, VMs have sometimes been used, e.g., in \href{https://is.ieis.tue.nl/staff/pvgorp/share}{SHARE} (which was awarded second prize in the Elsevier Executable Paper Grand Challenge of 2011 but was discontinued in 2019).
However, containers (in particular, Docker, and to a lesser degree, Singularity) are currently the most widely-used solution.
We will thus focus on Docker here.
-Ideally, it is possible to precisely identify the Docker ``images'' that are imported with their checksums, but that is rarely practiced in most solutions that we have surveyed.
-Usually, images are imported with generic operating system (OS) names; e.g., \cite{mesnard20} uses `\inlinecode{FROM ubuntu:16.04}'.
-The extracted tarball (from \url{https://partner-images.canonical.com/core/xenial}) is updated almost monthly and only the most recent five are archived.
-Hence, if the Dockerfile is run in different months, its output image will contain different OS components.
+\new{It is theoretically possible to precisely identify the used Docker ``images'' with their checksums (or ``digest'') to re-create an identical OS image later.

In the year 2024, when long-term support for this version of Ubuntu expires, the image will be unavailable at the expected URL.
Generally, Pre-built binary files (like Docker images) are large and expensive to maintain and archive.

-This prompted DockerHub (an online service to host Docker images, including many reproducible workflows) to delete images that have not been used for over 6 months.
-Furthermore, Docker requires root permissions, and only supports recent (``long-term-support'') versions of the host kernel, so older Docker images may not be executable.

+Furthermore, Docker requires root permissions, and only supports recent (``long-term-support'') versions of the host kernel, so older Docker images may not be executable \new{(their longevity is determined by the host kernel, usually a decade)}.
Once the host OS is ready, PMs are used to install the software or environment.
Usually the OS's PM, such as `\inlinecode{apt}' or `\inlinecode{yum}', is used first and higher-level software are built with generic PMs.
-The former suffers from the same longevity problem as the OS, while some of the latter (such as Conda and Spack) are written in high-level languages like Python, so the PM itself depends on the host's Python installation.
-Nix and GNU Guix produce bit-wise identical programs, but they need root permissions and are primarily targeted at the Linux kernel.
-Generally, the exact version of each software's dependencies is not precisely identified in the PM build instructions (although this could be implemented).
-Therefore, unless precise version identifiers of \emph{every software package} are stored by project authors, a PM will use the most recent version.
+The former has \new{the same longevity} as the OS, while some of the latter (such as Conda and Spack) are written in high-level languages like Python, so the PM itself depends on the host's Python installation \new{with a usual longevity of a few years}.
+Nix and GNU Guix produce bit-wise identical programs \new{with considerably better longevity; same as supported CPU architectures}.
+However, they need root permissions and are primarily targeted at the Linux kernel.

+Unless precise version identifiers of \emph{every software package} are stored by project authors, a PM will use the most recent version.
Furthermore, because third-party PMs introduce their own language, framework, and version history (the PM itself may evolve) and are maintained by an external team, they increase a project's complexity.
With the software environment built, job management is the next component of a workflow.
-Visual workflow tools like Apache Taverna, GenePattern, Kepler or VisTrails (mostly introduced in the 2000s and using Java) encourage modularity and robust job management, but the more recent tools (mostly in Python) leave this to the authors of the project.
-Designing a modular project needs to be encouraged and facilitated because scientists (who are not usually trained in project or data management) will rarely apply best practices.

+Designing a robust project needs to be encouraged and facilitated because scientists (who are not usually trained in project or data management) will rarely apply best practices.

+Besides non-reproducibility, weak project management leads to many inefficiencies in project cost and/or scientific accuracy (reusing, expanding, or validating will be expensive).
-Finally, to add narrative, computational notebooks \cite{rule18}, such as Jupyter, are currently gaining popularity.

-Further, as with job management, computational notebooks do not actively encourage good practices in programming or project management, hence they can rarely deliver their promised potential \cite{rule18} and may even hamper reproducibility \cite{pimentel19}.
+Furthermore, as with job management, computational notebooks do not actively encourage good practices in programming or project management.
+\new{The ``cells'' in a Jupyter notebook can either be run sequentially (from top to bottom, one after the other) or by manually selecting which cell to run.
+The default cells don't include dependencies (so some cells run only after certain others are re-done), parallel execution, or usage of more than one language.
+There are third party add-ons like \inlinecode{sos} or \inlinecode{nbextensions} (both written in Python) for some of these.
+However, since they aren't part of the core and have their own dependencies, their longevity can be assumed to be shorter.

+It is also itself written in Python (version 3.4 or above), hence it is not clear
+
+Furthermore, it also violates our complexity criteria because the instructions to build the software, their versions and etc are not immediately viewable or modifable by the user.
+Occam contains its own JSON database for this that should be parsed with its own custom program.
+The analysis phase of Occum is also through a drag-and-drop interface (similar to Taverna, Appendix \ref{appendix:taverna}) that is a web-based graphic user interface.
+All the connections between various phases of an analysis need to be pre-defined in a JSON file and manually linked in the GUI.
+Hence for complex data analysis operations with involve thousands of steps, it is not scalable.

+1. [EiC] Some reviewers request additions, and overview of other
+ tools.
+
+ANSWER: Indeed, there is already a large body work in various issues that
+have been touched upon in this paper. Before submitting the paper, we had
+already done a very comprehensive review of the tools (as you may notice
+from the Git repository[1]). However, the CiSE Author Information
+explicitly states: "The introduction should provide a modicum of background
+in one or two paragraphs, but should not attempt to give a literature
+review". This is also practiced in previously published papers at CiSE and
+is in line with the very limited word-count and maximum of 12 references to
+be used in bibliography.
+
+We were also eager to get that extensive review out (which took a lot of
+time, and most of the tools were actually run andtested). Hence we
+discussed this privately with the editors and this solution was agreed
+upon: we include that extended review as appendices on the arXiv[2] and
+Zenodo[3] pre-prints of this paper and mention those publicly available
+appendices in the submitted paper for an interested reader to followup.

+
+------------------------------
+
+
+
+
+
+2. [Associate Editor] There are general concerns about the paper
+ lacking focus
+
+ANSWER:
+
+------------------------------
+
+
+
+
+
+3. [Associate Editor] Some terminology is not well-defined
+ (e.g. longevity).
+
+ANSWER: It has now been clearly defined in the first paragraph of Section
+II. With this definition, the main argument of the paper much more clear,
+thank you (and the referees for highlighting this).
+
+------------------------------
+
+
+
+
+
+4. [Associate Editor] The discussion of tools could benefit from some
+ categorization to characterize their longevity.
+
+ANSWER: The longevity of the general tools reviewed in Section II are now
+mentioned immediately after each (highlighted in green).
+
+------------------------------
+
+
+
+
+
+5. [Associate Editor] Background and related efforts need significant
+ improvement. (See below.)
+
+ANSWER: This has been done, as mentioned in (1).
+
+------------------------------
+
+
+
+
+
+6. [Associate Editor] There is consistency among the reviews that
+ related work is particularly lacking.
+
+ANSWER: This has been done, as mentioned in (1).
+
+------------------------------
+
+
+
+
+
+7. [Associate Editor] The current work needs to do a better job of
+ explaining how it deals with the nagging problem of running on CPU
+ vs. different architectures.
+
+ANSWER: The CPU architecture of the running system is now reported in the
+"Acknowledgments" section and a description of the problem and its solution
+in Maneage is also added in the "Proof of concept: Maneage" Section.
+
+------------------------------
+
+
+
+
+
+8. [Associate Editor] At least one review commented on the need to
+ include a discussion of continuous integration (CI) and its
+ potential to help identify problems running on different
+ architectures. Is CI employed in any way in the work presented in
+ this article?
+
+ANSWER: CI has been added in the discussion as one solution to find
+breaking points in operating system updates and new/different
+architectures. For the core Maneage branch, we have defined task #15741 [1]
+to add CI on many architectures in the near future.
+
+[1] http://savannah.nongnu.org/task/?15741
+
+------------------------------
+
+
+
+
+
+9. [Associate Editor] The presentation of the Maneage tool is both
+ lacking in clarity and consistency with the public
+ information/documentation about the tool. While our review focus
+ is on the article, it is important that readers not be confused
+ when they visit your site to use your tools.
+
+###########################
+ANSWER [NOT COMPLETE]: We should separate the various sections of the
+README-hacking.md webpage into smaller pages that can be entered.
+###########################
+
+------------------------------
+
+
+
+
+
+10. [Associate Editor] A significant question raised by one review is
+ how this work compares to "executable" papers and Jupyter
+ notebooks. Does this work embody similar/same design principles
+ or expand upon the established alternatives? In any event, a
+ discussion of this should be included in background/motivation and
+ related work to help readers understand the clear need for a new
+ approach, if this is being presented as new/novel.
+
+ANSWER: Thank you for highlighting this important point. We saw that its
+necessary to contrast our proof of concept demonstration more directly with
+Maneage. Two paragraphs have been added in Sections II and IV for this.
+
+------------------------------
+
+
+
+
+
+11. [Reviewer 1] Adding an explicit list of contributions would make
+ it easier to the reader to appreciate these. These are not
+ mentioned/cited and are highly relevant to this paper (in no
+ particular order):
+ 1. Git flows, both in general and in particular for research.
+ 2. Provenance work, in general and with git in particular
+ 3. Reprozip: https://www.reprozip.org/
+ 4. OCCAM: https://occam.cs.pitt.edu/
+ 5. Popper: http://getpopper.io/
+ 6. Whole Tale: https://wholetale.org/
+ 7. Snakemake: https://github.com/snakemake/snakemake
+ 8. CWL https://www.commonwl.org/ and WDL https://openwdl.org/
+ 9. Nextflow: https://www.nextflow.io/
+ 10. Sumatra: https://pythonhosted.org/Sumatra/
+ 11. Podman: https://podman.io
+ 12. AppImage (https://appimage.org/)
+ 13. Flatpack (https://flatpak.org/)
+ 14. Snap (https://snapcraft.io/)
+ 15. nbdev https://github.com/fastai/nbdev and jupytext
+ 16. Bazel: https://bazel.build/
+ 17. Debian reproducible builds: https://wiki.debian.org/ReproducibleBuilds
+
+ANSWER:
+
+1. In Section IV, we have added that "Generally, any git flow (branching
+ strategies) can be used by the high-level project authors or future
+ readers."
+2. We have mentioned research objects as one mode of provenance tracking
+ and the related provenance work that has already been done and can be
+ exploited using these criteria and our proof of concept is indeed very
+ large. However, the 6250 word-count limit is very tight and if we add
+ more on it in this length, we would have to remove more directly
+ relevant points. Hopefully this can be the subject of a follow up
+ paper.
+3. A review of ReproZip is in Appendix B.
+4. A review of Occam is in Appendix B.
+5. A review of Popper is in Appendix B.
+6. A review of Whole tale is in Appendix B.
+7. A review of Snakemake is in Appendix A.
+8. CWL and WDL are described in Appendix A (job management).
+9. Nextflow is described in Appendix A (job management).
+10. Sumatra is described in Appendix B.
+11. Podman is mentioned in Appendix A (containers).
+12. AppImage is mentioned in Appendix A (package management).
+13. Flatpak is mentioned in Appendix A (package management).
+14. nbdev and jupytext are high-level tools to generate documentation and
+ packaging custom code in Conda or pypi. High-level package managers
+ like Conda and Pypi have already been thoroughly reviewed in Appendix A
+ for their longevity issues, so we feel there is no need to include
+ these.
+15. Bazel has been mentioned in Appendix A (job management).
+16. Debian's reproducible builds is only for ensuring that software
+ packaged for Debian are bitwise reproducible. As mentioned in the
+ discussion of this paper, the bitwise reproducibility of software is
+ not an issue in the context discussed here, the reproducibility of the
+ relevant output data of the software is the main issue.
+
+
+------------------------------
+
+
+
+
+
+12. [Reviewer 1] Existing guidelines similar to the proposed "Criteria
+ for longevity". Many articles of these in the form "10 simple
+ rules for X", for example (not exhaustive list):
+ * https://doi.org/10.1371/journal.pcbi.1003285
+ * https://arxiv.org/abs/1810.08055
+ * https://osf.io/fsd7t/
+ * A model project for reproducible papers: https://arxiv.org/abs/1401.2000
+ * Executable/reproducible paper articles and original concepts
+
+ANSWER: Thank you for highlighting these points. Appendix B starts with a
+subsection titled "suggested rules, checklists or criteria" that review of
+existing criteria. that include the proposed sources here (and others).
+
+arXiv:1401.2000 has been added in Appendix A as an example paper using
+virtual machines. We thank the referee for bringing up this paper, because
+the link to the VM provided in the paper no longer works (the file has been
+removed on the server). Therefore added with SHARE, it very nicely
+highlighting our main issue with binary containers or VMs and their lack of
+longevity.
+
+------------------------------
+
+
+
+
+
+13. [Reviewer 1] Several claims in the manuscript are not properly
+ justified, neither in the text nor via citation. Examples (not
+ exhaustive list):
+ 1. "it is possible to precisely identify the Docker “images” that
+ are imported with their checksums, but that is rarely practiced
+ in most solutions that we have surveyed [which ones?]"
+ 2. "Other OSes [which ones?] have similar issues because pre-built
+ binary files are large and expensive to maintain and archive."
+ 3. "Researchers using free software tools have also already had
+ some exposure to it"
+ 4. "A popular framework typically falls out of fashion and
+ requires significant resources to translate or rewrite every
+ few years."
+
+ANSWER: They have been clarified in the highlighted parts of the text:
+
+1. Many examples have been given throughout the newly added appendices. To
+ avoid confusion in the main body of the paper, we have removed the "we
+ have surveyed" part. It is already mentioned above it that a large
+ survey of existing methods/solutions is given in the appendices.
+
+2. Due to the thorough discussion of this issue in the appendices with
+ precise examples, this line has been removed to allow space for the
+ other points raised by the referees. The main point (high cost of
+ keeping binaries) is aldreay abundantly clear.
+
+ On a similar topic, Dockerhub's recent announcement that inactive images
+ (for over 6 months) will be deleted has also been added. The announcemnt
+ URL is here (it was too long to include in the paper, if IEEE has a
+ special short-url format, we can add it):
+ https://www.docker.com/blog/docker-hub-image-retention-policy-delayed-and-subscription-updates
+
+3. A small statement has been added, reminding the readers that almost all
+ free software projects are built with Make (note that CMake is just a
+ high-level wrapper over Make: it finally produces a 'Makefile').
+
+4. The example of Python 2 has been added.
+
+
+------------------------------
+
+
+
+
+
+14. [Reviewer 1] As mentioned in the discussion by the authors, not
+ even Bash, Git or Make is reproducible, thus not even Maneage can
+ address the longevity requirements. One possible alternative is
+ the use of CI to ensure that papers are re-executable (several
+ papers have been written on this topic). Note that CI is
+ well-established technology (e.g. Jenkins is almost 10 years old).
+
+ANSWER: Thank you for raising this issue. We had initially planned to add
+this issue also, but like many discussion points, we were forced to remove
+it before the first submission due to the very tight word-count limit. We
+have now added a sentence on CI in the discussion.
+
+On the initial note, indeed, the "executable" files of Bash, Git or Make
+are not bitwise reproducible/identical on different systems. However, as
+mentioned in the discussion, we are concerned with the _output_ of the
+software's executable file, _after_ the execution of its job. We (or any
+user of Bash) is not interested in the executable file itself. The
+reproducibility of the binary file only becomes important if a bug is found
+(very rare for common usage in such core software of the OS). Hence even
+though the compiled binary files of specific versions of Git, Bash or Make
+will not be bitwise reproducible/identical on different systems, their
+outputs are exactly reproducible: 'git describe' or Bash's 'for' loop will
+have the same output on GNU/Linux, macOS or FreeBSD (that produce bit-wise
+different executables).
+
+------------------------------
+
+
+
+
+
+15. [Reviewer 1] Criterion has been proposed previously. Maneage itself
+ provides little novelty (see comments below).
+
+ANSWER: The previously suggested criteria that were mentioned are reviewed
+in the newly added Appendix B, and the novelty/necessity of the proposed
+criteria is shown by comparison there.
+
+------------------------------
+
+
+
+
+
+16. [Reviewer 2] Authors should add indication that using good practices it
+ is possible to use Docker or VM to obtain identical OS usable for
+ reproducible research.
+
+ANSWER: In the submitted version we had stated that "Ideally, it is
+possible to precisely identify the Docker “images” that are imported with
+their checksums ...". But to be more clear and directly to the point, it
+has been edited to explicity say "... to recreate an identical OS image
+later".
+
+------------------------------
+
+
+
+
+
+17. [Reviewer 2] The CPU architecture of the platform used to run the
+ workflow is not discussed in the manuscript. Authors should probably
+ take into account the architecture used in their workflow or at least
+ report it.
+
+ANSWER: Thank you very much for raising this important point. We hadn't
+seen other reproducibility papers mention this important point and missed
+it. In the acknowledgments (where we also mention the commit hashes) we now
+explicity mention the exact CPU architecture used to build this paper:
+"This project was built on an x86_64 machine with Little Endian byte-order
+and address sizes 39 bits physical, 48 bits virtual.". This is because we
+have already seen cases where the architecture is the same, but programs
+fail because of the byte-order.
+
+Generally, Maneage will now extract this information from the running
+system during its configuration phase and provide the users with three
+different LaTeX macros that they can use anywhere in their paper.
+
+------------------------------
+
+
+
+
+
+18. [Reviewer 2] I don’t understand the "no dependency beyond
+ POSIX". Authors should more explained what they mean by this sentence.
+
+ANSWER: This has been clarified with the short extra statement "a minimal
+Unix-like standard that is shared between many operating systems". We would
+have liked to explain this more, but the word-limit is very constraining.
+
+------------------------------
+
+
+
+
+
+19. [Reviewer 2] Unfortunately, sometime we need proprietary or specialized
+ software to read raw data... For example in genetics, micro-array raw
+ data are stored in binary proprietary formats. To convert this data
+ into a plain text format, we need the proprietary software provided
+ with the measurement tool.
+
+ANSWER: Thank you very much for this good point. A description of a
+possible solution to this has been added after criteria 8.
+
+------------------------------
+
+
+
+
+
+20. [Reviewer 2] I was not able to properly set up a project with
+ Maneage. The configuration step failed during the download of tools
+ used in the workflow. This is probably due to a firewall/antivirus
+ restriction out of my control. How frequent this failure happen to
+ users?
+
+ANSWER: Thank you for mentioning this. This has been fixed by archiving all
+Maneage'd software on Zenodo (https://doi.org/10.5281/zenodo.3883409) and
+also downloading from there.
+
+Until recently we would directly access each software's own webpage to
+download the files, and this caused many problems like this. In other
+cases, we were very frustrated when a software's webpage would temporarily
+be unavailable (for maintainance reasons), this wouldn't allow us to build
+new projects.
+
+Since all the software are free, we are allowed to re-distribute them and
+Zenodo is defined for long-term archival of academic artifacts, so we
+figured that a software source code repository on Zenodo would be the most
+reliable solution. At configure time, Maneage now accesses Zenodo's DOI and
+resolves the most recent URL to automatically download any necessary
+software source code that the project needs from there.
+
+Generally, we also keep all software in a Git repository on our own
+webpage: http://git.maneage.org/tarballs-software.git/tree. Also, Maneage
+users can also identify their own custom URLs for downloading software,
+which will be given higher priority than Zenodo (useful for situations when
+a custom software is downloaded and built in a project branch (not the core
+'maneage' branch).
+
+------------------------------
+
+
+
+
+
+21. [Reviewer 2] The time to configure a new project is quite long because
+ everything needs to be compiled. Authors should compare the time
+ required to set up a project Maneage versus time used by other
+ workflows to give an indication to the readers.
+
+ANSWER: Thank you for raising this point. it takes about 1.5 hours to
+configure the default Maneage branch on an 8-core CPU (more than half of
+this time is devoted to GCC on GNU/Linux operating systems, and the
+building of GCC can optionally be disabled with the '--host-cc' option to
+significantly speed up the build when the host's GCC is
+similar). Furthermore, Maneage can be built within a Docker container.
+
+Generally, a paragraph has been added in Section IV on this issue (the
+build time and building within a Docker container). We have also defined
+task #15818 [1] to have our own core Docker image that is ready to build a
+Maneaged project and will be adding it shortly.
+
+[1] https://savannah.nongnu.org/task/index.php?15818
+
+------------------------------
+
+
+
+
+
+22. [Reviewer 3] Authors should define their use of the term [Replicability
+ or Reproducibility] briefly for their readers.
+
+ANSWER: "Reproducibility" has been defined along with "Longevity" and
+"usage" at the start of Section II.
+
+------------------------------
+
+
+
+
+
+23. [Reviewer 3] The introduction is consistent with the proposal of the
+ article, but deals with the tools separately, many of which can be used
+ together to minimize some of the problems presented. The use of
+ Ansible, Helm, among others, also helps in minimizing problems.
+
+ANSWER: Ansible and Helm are primarily designed for distributed
+computing. For example Helm is just a high-level package manager for a
+Kubernetes cluster that is based on containers. A review of them can be
+added in the Appendix, but we feel they may not be too relevant for this
+paper.
+
+------------------------------
+
+
+
+
+
+24. [Reviewer 3] When the authors use the Python example, I believe it is
+ interesting to point out that today version 2 has been discontinued by
+ the maintaining community, which creates another problem within the
+ perspective of the article.
+
+ANSWER: Thank you very much for highlighting this point it was not included
+for the sake of length, it has been fitted into the introduction now.
+
+------------------------------
+
+
+
+
+
+25. [Reviewer 3] Regarding the use of VM's and containers, I believe that
+ the discussion presented by THAIN et al., 2015 is interesting to
+ increase essential points of the current work.
+
+ANSWER: Thank you very much for pointing this the works by Thain. We
+couldn't find any first-author papers in 2015, but found Meng & Thain
+(https://doi.org/10.1016/j.procs.2017.05.116) which had a related
+discussion of why they didn't use Docker containers in their work. That
+paper is now cited in the discussion of Containers in Appendix A.
+
+------------------------------
+
+
+
+
+
+26. [Reviewer 3] About the Singularity, the description article was missing
+ (Kurtzer GM, Sochat V, Bauer MW, 2017).
+
+ANSWER: Thank you for the reference, we could not put it in the main body
+of the paper (like many others) due to the strict bibliography limit of 12,
+but it has been cited in Appendix A (where we discuss Singularity).
+
+------------------------------
+
+
+
+
+
+27. [Reviewer 3] I also believe that a reference to FAIR is interesting
+ (WILKINSON et al., 2016).
+
+ANSWER: The FAIR principles have been mentioned in the main body of the
+paper, but unfortunately we had to remove its citation the main paper (like
+MANY others) within the maximum limit 12 references. We have cited it in
+Appendix B.
+
+------------------------------
+
+
+
+
+
+28. [Reviewer 3] In my opinion, the paragraph on IPOL seems to be out of
+ context with the previous ones. This issue of end-to-end
+ reproducibility of a publication could be better explored, which would
+ further enrich the tool presented.
+

+
+
+
+
+
+29. [Reviewer 3] On the project website, I suggest that the information
+ contained in README-hacking be presented on the same page as the
+ Tutorial. A topic breakdown is interesting, as the markdown reading may
+ be too long to find information.

+
+
+
+31. [Reviewer 3] The tool is suitable for Unix users, keeping users away
+ from Microsoft environments.
+
+ANSWER: The issue of building on Windows has been discussed in Section IV,
+either using Docker (or VMs) or using the Windows Subsystem for Linux.
+
+------------------------------
+
+
+
+
+32. [Reviewer 3] Important references are missing; more references are
+ needed
+
+ANSWER: Two comprehensive Appendices have beed added to address this issue.
+
+------------------------------
+
+
+
+
+
+33. [Reviewer 4] Revisit the criteria, show how you have come to decide on
+ them, give some examples of why they are important, and address
+ potential missing criteria.
+
+for example the referee already points to "how code is written" as a
+criteria (for example for threading or floating point errors), or
+"performance".

+
+------------------------------
+
+
+
+
+

+ suited to this approach.
+
+################################
+ANSWER:
+################################
+
+------------------------------
+
+
+
+
+
+36. [Reviewer 4] There is also the challenge of mathematical
+ reproducibility, particularly of the handling of floating point number,
+ which might occur because of the way the code is written, and the
+ hardware architecture (including if code is optimised / parallelised).
+

+
+38. [Reviewer 4] Tradeoff, which might affect Criterion 3 is time to result,
+ people use popular frameworks because it is easier to use them.
+
+################################
+ANSWER:
+################################
+
+------------------------------
+
+
+
+
+
+39. [Reviewer 4] I would liked to have seen explanation of how these
+ challenges to adoption were identified: was this anecdotal, through
+ surveys? participant observation?
+
+ANSWER: The results mentioned here are based on private discussions after
+holding multiple seminars and Webinars with RDA's support, and also a
+workshop that was planned for non-astronomers. We even invited (funded)
+early career researchers to come to the workshop with the RDA funding,
+however, that workshop was cancelled due to the pandemic and we had private
+communications after.
+
+We would very much like to elaborate on this experience of training new
+researchers with these tools. However, as with many of the cases above, the
+very strict word-limit doesn't allow us to elaborate beyond what is already
+there.
+
+------------------------------
+
+
+
+
+
+40. [Reviewer 4] Potentially an interesting sidebar to investigate how
+ LaTeX/TeX has ensured its longevity!
+
+##############################
+ANSWER:
+##############################
+
+------------------------------
+
+
+
+
+
+41. [Reviewer 4] The title is not specific enough - it should refer to the
+ reproducibility of workflows/projects.
+
+##############################
+ANSWER:
+##############################
+
+------------------------------
+
+
+
+
+
+42. [Reviewer 4] Whilst the thesis stated is valid, it may not be useful to
+ practitioners of computation science and engineering as it stands.
+
+ANSWER: We would appreciate if you could clarify this point a little
+more. We have shown how it has already been used in many research projects
+(also outside of observational astronomy which is the first author's main
+background). It is precisely defined for computational science and
+engineering problems where _publication_ of the human-readable workflow
+source is also important.
+
+------------------------------
+
+
+
+
+
+43. [Reviewer 4] Longevity is not defined.
+
+ANSWER: It has been defined now at the start of Section II.
+
+------------------------------
+
+
+
+
+
+44. [Reviewer 4] Whilst various tools are discussed and discarded, no
+ attempt is made to categorise the magnitude of longevity for which they
+ are relevant. For instance, environment isolators are regarded by the
+ software preservation community as adequate for timescale of the order
+ of years, but may not be suitable for the timescale of decades where
+ porting and emulation are used.
+
+ANSWER: Statements on quantifying their longevity have been added in
+Section II. For example in the case of Docker images: "their longevity is
+determined by the host kernel, usually a decade", for Python packages:
+"Python installation with a usual longevity of a few years", for Nix/Guix:
+"with considerably better longevity; same as supported CPU architectures."
+
+------------------------------
+
+
+
+
+
+45. [Reviewer 4] The title of this section "Commonly used tools and their
+ longevity" is confusing - do you mean the longevity of the tools or the
+ longevity of the workflows that can be produced using these tools?
+ What happens if you use a combination of all four categories of tools?
+
+##########################
+ANSWER:
+##########################
+
+------------------------------
+
+
+
+
+
+46. [Reviewer 4] It wasn't clear to me if code was being run to generate
+ the results and figures in a LaTeX paper that is part of a project in
+ Maneage. It appears to be suggested this is the case, but Figure 1
+ doesn't show how this works - it just has the LaTeX files, the data
+ files and the Makefiles. Is it being suggested that LaTeX itself is the
+ programming language, using its macro functionality?
+
+ANSWER: Thank you for highlighting this point of confusion. The caption of
+Figure 1 has been edited to hopefully clarify the point. In short, the
+arrows represent the operation of software on their inputs (the file they
+originate from) to generate their outputs (the file they point to). In the
+case of generating 'paper.pdf' from its three dependencies
+('references.tex', 'paper.tex' and 'project.tex'), yes, LaTeX is used. But
+in other steps, other tools are used. For example as you see in [1] the
+main step of the arrow connecting 'table-3.txt' to 'tools-per-year.txt' is
+an AWK command (there are also a few 'echo' commands for meta data and
+copyright in the output plain-text file [2]).

+
+------------------------------
+
+
+
+
+
+47. [Reviewer 4] I was a bit confused on how collaboration is handled as
+ well - this appears to be using the Git branching model, and the
+ suggestion that Maneage is keeping track of all components from all
+ projects - but what happens if you are working with collaborators that
+ are using their own Maneage instance?
+
+ANSWER: Indeed, Maneage operates based on the Git branching model. As
+mentioned in the text, Maneage is itself a Git branch. People create their
+own branch from the 'maneage' branch and start customizing it for their
+particular project in their own particular repository. They can also use
+all types of Git-based collaborating models to work together on a project
+that is not yet finished.
+
+Figure 2 infact explicitly shows such a case: the main project leader is
+committing on the "project" branch. But a collaborator creates a separate
+branch over commit '01dd812' and makes a couple of commits ('f69e1f4' and
+'716b56b'), and finally asks the project leader to merge them into the
+project. This can be generalized to any Git based collaboration model.
+
+------------------------------
+
+
+
+
+
+48. [Reviewer 4] I would also liked to have seen a comparison between this
+ approach and other "executable" paper approaches e.g. Jupyter
+ notebooks, compared on completeness, time taken to write a "paper",
+ ease of depositing in a repository, and ease of use by another
+ researcher.
+
+#######################
+ANSWER:
+#######################
+
+------------------------------
+
+
+
+
+
+49. [Reviewer 4] The weakest aspect is the assumption that research can be
+ easily compartmentalized into simple and complete packages. Given that
+ so much of research involves collaboration and interaction, this is not
+ sufficiently addressed. In particular, the challenge of
+ interdisciplinary work, where there may not be common languages to
+ describe concepts and there may be different common workflow practices
+ will be a barrier to wider adoption of the primary thesis and criteria.
+
+ANSWER: Maneage was precisely defined to address the problem of
+publishing/collaborating on complete workflows. Hopefully with the
+clarification to point 47 above, this should also become clear.
+
+------------------------------
+
+
+
+
+
+50. [Reviewer 5] Major figures currently working in this exact field do not
+ have their work acknowledged in this work.
+
+ANSWER: This was due to the strict word limit and the CiSE publication
+policy (to not include a literature review because there is a limit of only
+12 citations). But we had indeed done a comprehensive literature review and
+the editors kindly agreed that we publish that review as appendices to the
+main paper on arXiv and Zenodo.
+
+------------------------------
+
+
+
+
+
+51. [Reviewer 5] The popper convention: Making reproducible systems
+ evaluation practical ... and the later revision that uses GitHub
+ Actions, is largely the same as this work.
+
+ANSWER: This work and the proposed criteria are very different from
+Popper. A review of Popper has been given in Appendix B.
+
+------------------------------
+
+
+
+
+
+52. [Reviewer 5] The lack of attention to virtual machines and containers
+ is highly problematic. While a reader cannot rely on DockerHub or a
+ generic OS version label for a VM or container, these are some of the
+ most promising tools for offering true reproducibility.
+
+ANSWER: Containers and VMs have been more thoroughly discussed in the main
+body and also extensively discussed in appendix A (that are now available
+in the arXiv and Zenodo versions of this paper). As discussed (with many
+cited examples), Contains and VMs are only good when they are themselves
+reproducible (for example running the Dockerfile this year and next year
+gives the same internal environment). However we show that this is not the
+case in most solutions (a more comprehensive review would require its own
+paper).
+
+However with complete/robust environment builders like Maneage, Nix or GNU
+Guix, the analysis environment within a container can be exactly reproduced
+later. But even so, due to their binary nature and large storage volume,
+they are not trusable sources for the long term (it is expensive to archive
+them). We show several example in the paper of how projects that relied on
+VMs in 2011 and 2014 are no longer active, and how even Dockerhub will be
+deleting containers that are not used for more than 6 months in free
+accounts (due to the large storage costs).
+
+------------------------------
+
+
+
+
+
+53. [Reviewer 5] On the data side, containers have the promise to manage
+ data sets and workflows completely [Lofstead J, Baker J, Younge A. Data
+ pallets: containerizing storage for reproducibility and
+ traceability. InInternational Conference on High Performance Computing
+ 2019 Jun 16 (pp. 36-45). Springer, Cham.] Taufer has picked up this
+ work and has graduated a MS student working on this topic with a
+ published thesis. See also Jimenez's P-RECS workshop at HPDC for
+ additional work highly relevant to this paper.
+
+ANSWER: Thank you for the interesting paper by Lofstead+2019 on Data
+pallets. We have cited it in Appendix A as examples of how generic the
+concept of containers is.
+
+The topic of linking data to analysis is also a core result of the criteria
+presented here, and is also discussed shortly in the paper. There are
+indeed many very interesting works on this topic. But the format of CiSE is
+very short (a maximum of ~6000 words with 12 references), so we don't have
+the space to go into this any further. But this is indeed a very
+interesting aspect for follow up studies, especially as the usage of
+Maneage incrases, and we have more example workflows by users to study the
+linkage of data analysis.
+
+------------------------------
+
+
+
+
+
+54. [Reviewer 5] Some other systems that do similar things include:
+ reprozip, occam, whole tale, snakemake.
+
+ANSWER: All these tools have been reviewed in the newly added appendices.
+
+------------------------------
+
+
+
+
+
+55. [Reviewer 5] the paper needs to include the context of the current
+ community development level to be a complete research paper. A revision
+ that includes evaluation of (using the criteria) and comparison with
+ the suggested systems and a related work section that seriously
+ evaluates the work of the recommended authors, among others, would make
+ this paper worthy for publication.
+
+ANSWER: A thorough review of current low-level tools and and high-level
+reproducible workflow management systems has been added in the extended
+Appendix.
+
+------------------------------
+
+
+
+
+
+56. [Reviewer 5] Offers criteria any system that offers reproducibility
+ should have.
+
+ANSWER:
+
+------------------------------
+
+
+
+
+
+57. [Reviewer 5] Yet another example of a reproducible workflows project.
+
+ANSWER: As the newly added thorough comparisons with existing systems
+shows, these set of criteria and the proof-of-concept offer uniquely new
+features. As another referee summarized: "This manuscript describes a new
+reproducible workflow which doesn't require another new trendy high-level
+software. The proposed workflow is only based on low-level tools already
+widely known."
+
+The fact that we don't define yet another workflow language and framework
+and base the whole workflow on time-tested solutions in a framwork that
+costs only ~100 kB to archive (in contrast to multi-GB containers or VMs)
+is new.
+
+------------------------------
+
+
+
+
+
+58. [Reviewer 5] There are numerous examples, mostly domain specific, and
+ this one is not the most advanced general solution.
+
+ANSWER: As the comparisons in the appendices and clarifications above show,
+there are many features in the proposed criteria and proof of concept that
+are new.
+
+------------------------------
+
+
+
+
+
+59. [Reviewer 5] Lack of context in the field missing very relevant work
+ that eliminates much, if not all, of the novelty of this work.
+
+ANSWER: The newly added appendices thoroughly describe the context and
+previous work that has been done in this field.

+
+Comments of the Associate Editor: Associate Editor
+Comments to the Author: Thank to the authors for your submission to the
+Reproducible Research department.
+
+Thanks to the reviewers for your careful and thoughtful reviews. We would
+appreciate it if you can make your reports available and share the DOI as
+soon as possible, per our original invitation e-mail. We will follow up our
+original invitation to obtain your review DOI, if you have not already
+included it in your review comments.
+
+Based on the review feedback, there are a number of major issues that
+require attention and many minor ones as well. Please take these into
+account as you prepare your major revision for another round of
+review. (See the actual review reports for details.)
+
+1. In general, there are a number of presentation issues needing
+attention. There are general concerns about the paper lacking focus. Some
+terminology is not well-defined (e.g. longevity). In addition, the
+discussion of tools could benefit from some categorization to characterize
+their longevity. Background and related efforts need significant
+improvement. (See below.)
+
+2. There is consistency among the reviews that related work is particularly
+lacking and not taking into account major works that have been written on
+this topic. See the reviews for details about work that could potentially
+be included in the discussion and how the current work is positioned with
+respect to this work.
+
+3. The current work needs to do a better job of explaining how it deals
+with the nagging problem of running on CPU vs. different architectures. At
+least one review commented on the need to include a discussion of
+continuous integration (CI) and its potential to help identify problems
+running on different architectures. Is CI employed in any way in the work
+presented in this article?
+
+4. The presentation of the Maneage tool is both lacking in clarity and
+consistency with the public information/documentation about the tool. While
+our review focus is on the article, it is important that readers not be
+confused when they visit your site to use your tools.
+
+5. A significant question raised by one review is how this work compares to
+"executable" papers and Jupyter notebooks. Does this work embody
+similar/same design principles or expand upon the established alternatives?
+In any event, a discussion of this should be included in
+background/motivation and related work to help readers understand the clear
+need for a new approach, if this is being presented as new/novel.
+
+Reviews:
+
+Please note that some reviewers may have included additional comments in a
+separate file. If a review contains the note "see the attached file" under
+Section III A - Public Comments, you will need to log on to ScholarOne
+Manuscripts to view the file. After logging in, select the Author Center,
+click on the "Manuscripts with Decisions" queue and then click on the "view
+decision letter" link for this manuscript. You must scroll down to the very
+bottom of the letter to see the file(s), if any. This will open the file
+that the reviewer(s) or the Associate Editor included for you along with
+their review.

+ * https://osf.io/fsd7t/
+
+ * A model project for reproducible papers: https://arxiv.org/abs/1401.2000
+
+ * Executable/reproducible paper articles and original concepts
+
+ * Several claims in the manuscript are not properly justified, neither in
+ the text nor via citation. Examples (not exhaustive list):
+
+ * "it is possible to precisely identify the Docker “images” that are
+ imported with their checksums, but that is rarely practiced in most
+ solutions that we have surveyed [which ones?]"
+
+ * "Other OSes [which ones?] have similar issues because pre-built
+ binary files are large and expensive to maintain and archive."
+
+ * "Researchers using free software tools have also already had some
+ exposure to it"
+
+ * "A popular framework typically falls out of fashion and requires
+ significant resources to translate or rewrite every few years."
+
+ * As mentioned in the discussion by the authors, not even Bash, Git or
+ Make is reproducible, thus not even Maneage can address the longevity
+ requirements. One possible alternative is the use of CI to ensure that
+ papers are re-executable (several papers have been written on this
+ topic). Note that CI is well-established technology (e.g. Jenkins is
+ almost 10 years old).

+Reviewer: 2
+Recommendation: Accept If Certain Minor Revisions Are Made
+
+Comments: https://doi.org/10.22541/au.159724632.29528907
+
+Operating System: Authors mention that Docker is usually used with an image
+of Ubuntu without precision about the version used. And Even if users take
+care about the version, the image is updated monthly thus the image used
+will have different OS components based on the generation time. This
+difference in OS components will interfere on the reproducibility. I agree
+on that, but I would like to add that it is a wrong habit of users. It is
+possible to generate reproducible Docker images by generating it from an
+ISO image of the OS. These ISO images are archived, at least for Ubuntu
+(http://old-releases.ubuntu.com/releases) and for Debian
+(https://cdimage.debian.org/mirror/cdimage/archive) thus allow users to
+generate an OS with identical components. Combined with the
+snapshot.debian.org service, it is even possible to update a Debian release
+to a specific time point up to 2005 and with a precision of six hours. With
+combination of both ISO image and snapshot.debian.org service it is
+possible to obtain an OS for Docker or for a VM with identical components
+even if users have to use the PM of the OS. Authors should add indication
+that using good practices it is possible to use Docker or VM to obtain
+identical OS usable for reproducible research.
+
+CPU architecture: The CPU architecture of the platform used to run the
+workflow is not discussed in the manuscript. During software integration in
+Debian, I have seen several software failing their unit tests due to
+different behavior from itself or from a library dependency. This not
+expected behavior was only present on non-x86 architectures, mainly because
+developers use a x86 machine for their developments and tests. Bug or
+feature? I don’t know, but nowadays, it is quite frequent to see computers
+with a non-x86 CPU. It would be annoying to fail the reproducibility step
+because of a different in CPU architecture. Authors should probably take
+into account the architecture used in their workflow or at least report it.
+
+POSIX dependency: I don’t understand the "no dependency beyond
+POSIX". Authors should more explained what they mean by this sentence. I
+completely agree that the dependency hell must be avoided and dependencies
+should be used with parsimony. Unfortunately, sometime we need proprietary
+or specialized software to read raw data. For example in genetics,
+micro-array raw data are stored in binary proprietary formats. To convert
+this data into a plain text format, we need the proprietary software
+provided with the measurement tool.
+
+Maneage: I was not able to properly set up a project with Maneage. The
+configuration step failed during the download of tools used in the
+workflow. This is probably due to a firewall/antivirus restriction out of
+my control. How frequent this failure happen to users? Moreover, the time
+to configure a new project is quite long because everything needs to be
+compiled. Authors should compare the time required to set up a project
+Maneage versus time used by other workflows to give an indication to the
+readers.
+
+Disclaimer: For the sake of transparency, it should be noted that I am
+involved in the development of Debian, thus my comments are probably
+oriented.

+Reviewer: 3
+Recommendation: Accept If Certain Minor Revisions Are Made
+
+Comments: Longevity of workflows in a project is one of the problems for
+reproducibility in different fields of computational research. Therefore, a
+proposal that seeks to guarantee this longevity becomes relevant for the
+entire community, especially when it is based on free software and is easy
+to access and implement.
+
+GOODMAN et al., 2016, BARBA, 2018 and PLESSER, 2018 observed in their
+research that the terms reproducibility and replicability are frequently
+found in the scientific literature and their use interchangeably ends up
+generating confusion due to the authors' lack of clarity. Thus, authors
+should define their use of the term briefly for their readers.
+
+The introduction is consistent with the proposal of the article, but deals
+with the tools separately, many of which can be used together to minimize
+some of the problems presented. The use of Ansible, Helm, among others,
+also helps in minimizing problems. When the authors use the Python example,
+I believe it is interesting to point out that today version 2 has been
+discontinued by the maintaining community, which creates another problem
+within the perspective of the article. Regarding the use of VM's and
+containers, I believe that the discussion presented by THAIN et al., 2015
+is interesting to increase essential points of the current work. About the
+Singularity, the description article was missing (Kurtzer GM, Sochat V,
+Bauer MW, 2017). I also believe that a reference to FAIR is interesting
+(WILKINSON et al., 2016).
+
+In my opinion, the paragraph on IPOL seems to be out of context with the
+previous ones. This issue of end-to-end reproducibility of a publication
+could be better explored, which would further enrich the tool presented.
+
+The presentation of the longevity criteria was adequate in the context of
+the article and explored the points that were dealt with later.
+
+The presentation of the tool was consistent. On the project website, I
+suggest that the information contained in README-hacking be presented on
+the same page as the Tutorial. A topic breakdown is interesting, as the
+markdown reading may be too long to find information.

+3. What do you see as this manuscript's contribution to the literature in
+ this field?: In this article, the authors discuss the problem of the
+ longevity of computational workflows, presenting what they consider to
+ be criteria for longevity and an implementation based on these criteria,
+ called Maneage, seeking to ensure a long lifespan for analysis projects.
+
+ As a key point, the authors enumerate quite clear criteria that can
+ guarantee the longevity of projects and present a free software-based
+ way of achieving this objective. The method presented by the authors is

+
+4. What do you see as the strongest aspect of this manuscript?: One of the
+ strengths of the manuscript is the implementation of Maneage entirely in
+ free software and the search for completeness presented in the
+ manuscript. The use of GNU software adds the guarantee of long
+ maintenance by one of the largest existing software communities. In
+ addition, the tool developed has already been tested in different
+ publications, showing itself consistent in different scenarios.
+
+5. What do you see as the weakest aspect of this manuscript?: For the
+ proper functioning of the proposed tool, the user needs prior knowledge
+ of LaTeX, GIT and the command line, which can keep inexperienced users
+ away. Likewise, the tool is suitable for Unix users, keeping users away
+ from Microsoft environments.
+
+ Even though Unix-like environments are the majority in the areas of
+ scientific computing, many users still perform their analysis in
+ different areas on Windows computers or servers, with the assistance of
+ package managers.

+Reviewer: 4
+Recommendation: Author Should Prepare A Major Revision For A Second Review
+
+Comments: Overall evaluation - Good.
+
+This paper is in scope, and the topic is of interest to the readers of
+CiSE. However in its present form, I have concerns about whether the paper
+presents enough new contributions to the area in a way that can then be
+understood and reused by others. The main things I believe need addressing
+are: 1) Revisit the criteria, show how you have come to decide on them,
+give some examples of why they are important, and address potential missing
+criteria. 2) Clarify the discussion of challenges to adoption and make it
+clearer which tradeoffs are important to practitioners. 3) Be clearer about
+which sorts of research workflow are best suited to this approach.
+
+B2.Technical soundness: here I am discussing the soundness of the paper,
+rather than the soundness of the Maneage tool. There are some fundamental
+additional challenges to reproducibility that are not addressed. Although
+software library versions are addressed, there is also the challenge of
+mathematical reproducibility, particularly of the handling of floating
+point number, which might occur because of the way the code is written, and
+the hardware architecture (including if code is optimised /
+parallelised). This could obviously be addressed through a criterion around
+how code is written, but this will also come with a tradeoff against
+performance, which is never mentioned. Another tradeoff, which might affect
+Criterion 3 is time to result - people use popular frameworks because it is
+easier to use them. Regarding the discussion, I would liked to have seen
+explanation of how these challenges to adoption were identified: was this
+anecdotal, through surveys. participant observation? As a side note around
+the technical aspects of Maneage - it is using LaTeX which in turn is built
+on TeX which in turn has had many portability problems in the past due to
+being written using WEB / Tangle, though with web2c this is largely now
+resolved - potentially an interesting sidebar to investigate how LaTeX/TeX
+has ensured its longevity!
+
+C2. The title is not specific enough - it should refer to the
+reproducibility of workflows/projects.
+
+C4. As noted above, whilst the thesis stated is valid, it may not be useful
+to practitioners of computation science and engineering as it stands.
+
+C6. Manuscript focus. I would have liked a more focussed approach to the
+presentation of information in II. Longevity is not defined, and whilst
+various tools are discussed and discarded, no attempt is made to categorise
+the magnitude of longevity for which they are relevant. For instance,
+environment isolators are regarded by the software preservation community
+as adequate for timescale of the order of years, but may not be suitable
+for the timescale of decades where porting and emulation are used. The
+title of this section "Commonly used tools and their longevity" is also
+confusing - do you mean the longevity of the tools or the longevity of the
+workflows that can be produced using these tools? What happens if you use a
+combination of all four categories of tools?
+
+C8. Readability. I found it difficult to follow the description of how
+Maneage works. It wasn't clear to me if code was being run to generate the
+results and figures in a LaTeX paper that is part of a project in
+Maneage. It appears to be suggested this is the case, but Figure 1 doesn't
+show how this works - it just has the LaTeX files, the data files and the
+Makefiles. Is it being suggested that LaTeX itself is the programming
+language, using its macro functionality? I was a bit confused on how
+collaboration is handled as well - this appears to be using the Git
+branching model, and the suggestion that Maneage is keeping track of all
+components from all projects - but what happens if you are working with
+collaborators that are using their own Maneage instance?
+
+I would also liked to have seen a comparison between this approach and
+other "executable" paper approaches e.g. Jupyter notebooks, compared on
+completeness, time taken to write a "paper", ease of depositing in a
+repository, and ease of use by another researcher.
+
+Additional Questions:
+
+1. How relevant is this manuscript to the readers of this periodical?
+ Please explain your rating in the Detailed Comments section.: Relevant
+
+2. To what extent is this manuscript relevant to readers around the world?:
+ The manuscript is of interest to readers throughout the world
+
+1. Please summarize what you view as the key point(s) of the manuscript and
+ the importance of the content to the readers of this periodical.: This
+ manuscript discusses the challenges of reproducibility of computational
+ research workflows, suggests criteria for improving the "longevity" of
+ workflows, describes the proof-of-concept tool, Maneage, that has been
+ built to implement these criteria, and discusses the challenges to
+ adoption.
+
+ Of primary importance is the discussion of the challenges to adoption,
+ as CiSE is about computational science which does not take place in a
+ theoretical vacuum. Many of the identified challenges relate to the
+ practice of computational science and the implementation of systems in
+ the real world.
+
+2. Is the manuscript technically sound? Please explain your answer in the
+ Detailed Comments section.: Partially
+
+3. What do you see as this manuscript's contribution to the literature in
+ this field?: The manuscript makes a modest contribution to the
+ literature through the description of the proof-of-concept, in
+ particular its approach to integrating asset management, version control
+ and build and the discussion of challenges to adoption.
+
+ The proposed criteria have mostly been discussed at length in many other
+ works looking at computational reproducibility and executable papers.
+
+4. What do you see as the strongest aspect of this manuscript?: The
+ strongest aspect is the discussion of difficulties for widespread
+ adoption of this sort of approach. Because the proof-of-concept tool
+ received support through the RDA, it was possible to get feedback from
+ researchers who were likely to use it. This has highlighted and
+ reinforced a number of challenges and caveats.
+
+5. What do you see as the weakest aspect of this manuscript?: The weakest
+ aspect is the assumption that research can be easily compartmentalized
+ into simple and complete packages. Given that so much of research
+ involves collaboration and interaction, this is not sufficiently
+ addressed. In particular, the challenge of interdisciplinary work, where
+ there may not be common languages to describe concepts and there may be
+ different common workflow practices will be a barrier to wider adoption
+ of the primary thesis and criteria.

+Recommendation: Author Should Prepare A Major Revision For A Second Review
+
+Comments:
+
+Major figures currently working in this exact field do not have their work
+acknowledged in this work. In no particular order: Victoria Stodden,
+Michael Heroux, Michela Taufer, and Ivo Jimenez. All of these authors have
+multiple publications that are highly relevant to this paper. In the case
+of Ivo Jimenez, his Popper work [Jimenez I, Sevilla M, Watkins N, Maltzahn
+C, Lofstead J, Mohror K, Arpaci-Dusseau A, Arpaci-Dusseau R. The popper
+convention: Making reproducible systems evaluation practical. In2017 IEEE
+International Parallel and Distributed Processing Symposium Workshops
+(IPDPSW) 2017 May 29 (pp. 1561-1570). IEEE.] and the later revision that
+uses GitHub Actions, is largely the same as this work. The lack of
+attention to virtual machines and containers is highly problematic. While a
+reader cannot rely on DockerHub or a generic OS version label for a VM or
+container, these are some of the most promising tools for offering true
+reproducibility. On the data side, containers have the promise to manage
+data sets and workflows completely [Lofstead J, Baker J, Younge A. Data
+pallets: containerizing storage for reproducibility and
+traceability. InInternational Conference on High Performance Computing 2019
+Jun 16 (pp. 36-45). Springer, Cham.] Taufer has picked up this work and has
+graduated a MS student working on this topic with a published thesis. See
+also Jimenez's P-RECS workshop at HPDC for additional work highly relevant
+to this paper.
+
+Some other systems that do similar things include: reprozip, occam, whole
+tale, snakemake.
+
+While the work here is a good start, the paper needs to include the context
+of the current community development level to be a complete research
+paper. A revision that includes evaluation of (using the criteria) and
+comparison with the suggested systems and a related work section that
+seriously evaluates the work of the recommended authors, among others,
+would make this paper worthy for publication.
