@dblarremore @tkonolige :wave: Welcome and thanks for agreeing to review! The comments from @whedon above outline the review process, which takes place in this thread (possibly with issues filed in the project repository). I'll be watching this thread if you have any questions.
@ScottKolo I think https://doi.org/10.1007/978-1-5041-2940-4_9 is the correct doi for Matrix market: A web resource for test matrix collections. It would be great if you can add that.
I also see that there is no documentation for building, installing, and testing locally. I created an issue for it in your repository: ScottKolo/suitesparse-matrix-collection-website#5.
@jedbrown I'm not sure about the example usage and functional documentation parts of the checklist. Does there need to be documentation on how to use the website? I think it is pretty straight forward.
I don't think human "use" of the website needs separate documentation, but there appears to be an API used by several external packages and I don't immediately notice documentation of that API.
I don't think human "use" of the website needs separate documentation, but there appears to be an API used by several external packages and I don't immediately notice documentation of that API.
We do include information about other interfaces to the Collection on the website itself on the Interfaces page. I also just added information in the repository README referencing the Interfaces page and also the URL routing feature, which might be considered an API.
The use of most of the website should be (we hope) easy enough to understand and figure out. We also include tooltips to help users with certain terminology:

Regarding the inner workings of things like UFget/ssget, we considered that somewhat out of scope for this paper as these interfaces were presented in Davis and Hu and are not strictly considered part of the web application. For example, these interfaces often provide the option to download a matrix, and that download URL is the same URL being used by the web application when you click the button on the website. The files are also not served by the Rails web application we've presented - they're being served by a file server. The way we see it, this is a "frontend" to access the "backend" presented in Davis and Hu.
That all makes sense. I think you're good on the documentation front then.
@ScottKolo, @jedbrown should the release version listed here be bumped to match what is currently in the repository (now that some changes have been made)?
Yeah, we'll ask for a tagged release at acceptance, and the version will be set at that time.
Trivial: "applicaiton" typo in README.
Perhaps more useful: Possible change needed in installation instructions for OSX.
I tried to do the local installation, updated Ruby, and got all of that sorted out. On README line
bundle exec rake db:setup
I kept getting an error
PG::ConnectionBad: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
I eventually fixed this by (apparently) manually starting the server via the top answer here whose details are then described in detail here.
After that, my local installation was totally fine.
To recap, my experience required that I insert this line between the bundle install and bundle exec rake commands:
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
Now, the question: is this worth inserting into the documentation? Are there files that could be modified by @ScottKolo or is this a sort of novice ruby user thing? (I am basically a test case for _user who does not know what he is doing with a local ruby installation_ so perhaps not an issue.) Curious to hear what you guys think.
To recap, my experience required that I insert this line between the bundle install and bundle exec rake commands:
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start
After installing PostgreSQL, one needs to start it up so it's running in the background. You can do this a number of ways: manually start/stop, use the daemon, etc. After installing PostgreSQL from a package manager, it often spits out a line at the end about this (i.e. "run this magical incantation to start the daemon").
I'm happy to add whatever you think is helpful to the documentation. I might suggest the following additional call to pg_isready:
ruby -v # Check that Ruby 2.5+ is installed
pg_isready # Check that PostgreSQL database is ready
git clone https://github.com/ScottKolo/suitesparse-matrix-collection-website.git
cd suitesparse-matrix-collection-website
gem install bundler:1.16.6 # Dependency manager
bundle install --without production # Download and install dependencies
bundle exec rake db:setup # Generate and seed the database
bundle exec rails server # Start the Ruby on Rails server application
Unfortunately, if pg_isready fails, it is not very informative regarding how to fix the problem.
I can add a line mentioning something about "PostgreSQL must be running - if it is not, try running pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start."
My only concern is that the above command assumes the user's postgres installation directory and log file location.
I like the idea to use pg_isready but how about putting this snippet above, under the bullet list that includes the need for ruby and postgreSQL? Then it would be filed in with the prep work and dependencies instead of with the installation itself.
What you wrote was really nice, so I tinkered with it a little, but maybe something like this? Happy for any modifications to this, since it's your README, but thought this might be useful:
After installing PostgreSQL, note that one needs to start it up so it's running in the background. The status can be checked using
pg_isready. If this fails, the installation can be started manually, e.g. viapg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start, depending on the location of your installation. If PostgreSQL was installed from a package manager, it often spits out a line at the end about this (i.e. "run this magical incantation to start the daemon").
If you think this is an ok suggestion, and decide to put the pg_isready note above in the dependencies, it might also be appropriate to move the ruby -v check up there as well.
With a little of my own wordsmithing, I have added information about starting PostgreSQL and installing Ruby to the README. Let me know if you think it's too much or not enough.

Looks great. Not overly verbose, but still thorough enough to capture users like me.
Just following up - is there any further feedback or any actions required on our part? What are the next steps?

Whedon is quite flaky about checking DOIs; they look fine in the paper. I made a PR for some bib formatting issues: https://github.com/ScottKolo/suitesparse-matrix-collection-website/pull/6
I think we'll be ready to archive and accept if that looks reasonable. Thanks for your patience.

I think Whedon only checks DOIs for @article entries currently. I'll see if I can fix this.

This article is a preprint on arXiv. The suggested DOI points to an unrelated article in physics.
@whedon generate pdf
Attempting PDF compilation. Reticulating splines etc...
Yeah, the DOI checker is very buggy. References look good to me now. Can you fix one spelling error "constrainted", tag a release (annotated tag preferred), and archive on Zenodo or similar?
@whedon generate pdf
Attempting PDF compilation. Reticulating splines etc...
One last nitpick: Is there any way to prevent line breaks in the middle of URLs?

I would consider dropping the https:// part because it's arguably clutter given that full links are embedded. and/or using a tt font:
[`https://sparse.tamu.edu/Mycielski`](https://sparse.tamu.edu/Mycielski)

Okay, I have tagged release at JOSS-1.0.2.
https://github.com/ScottKolo/suitesparse-matrix-collection-website/releases/tag/JOSS-1.0.2
We have archived the code for this release using figshare: https://figshare.com/articles/SuiteSparse_Matrix_Collection_Website/7381076
Does all of that look correct?
Author list on the figshare appears to be missing Yifan Hu, who was on the paper. Can you fix the author lists to match in content and order?
Fixed. The Figshare DOI is https://doi.org/10.6084/m9.figshare.7381076
The title now matches, as do the authors and author order.
@whedon set JOSS-1.0.2 as version
OK. JOSS-1.0.2 is the version.
@ScottKolo Is it intended that https:// appears in exactly one of the URLs?
Yes. We removed it for most as you suggested, since it wasnโt helpful in those contexts, but left it when we referenced its deployment location.
@whedon set 10.6084/m9.figshare.7381076 as archive
OK. 10.6084/m9.figshare.7381076 is the archive.
Over to you, @openjournals/joss-eics.
