Repology wikidata bot

Update Wikidata entries using information from Repology.

This bot iterates over software projects listed Repology which have associated (by specifying Repology project name property for a software project in Wikidata) Wikidata entry, and fills package information (such as Gentoo package property).

Dependencies

• Python 3.7+
• Python module Jinja2
• Python module pywikibot
• Python module requests

Modules can be installed with pip install -r requirements.txt command.

Running

The bot would run out of box, without any required arguments to specify, however if you're going to use another bot account than Repology bot, you'll need to edit user-config.py accordingly first.

By default, the bot processes all available projects (may take some time), and works with all supported package properties. It would list all changes it's going to make and ask you before doing any modifications, so running it just to see how it goes is safe.

The intended workflow is to run the bot with --html <output file> option to generate a verbose report, review the report and then confirm it's actions to perform modifications to Wikidata. You shouldn't generally need options apart from --html, but at start you may also use something like --from a --to b to limit operation on a fraction of projects (here: on projects starting with a letter), to get results faster and have a smaller set of items to review.

The bot generates a set of so called actions, which describe changes to be made, but it doesn't support performing all of them on its own - in fact, most actions are informational or need a manual intervention.

Types of actions

• Add property (displayed as green in reports). This is the only kind of action the bot may perform on its own. It's going to add missing properties to Wikidata.
• Remove property (displayed as red). This suggests that a property present in Wikidata is absent in Repology, either before Repology has incomplete data or because the package was in fact removed and Wikidata should be updated accordingly (by adding "end time" qualifier). Since this is unreliable and requires manual confirmation (and digging for relevant reference url), this is to be performed manually. The bot supplies some useful URLs to help with digging.
  • Subset of this is when property with "no data" value is encountered in Wikidata: this is likely an error and should be removed right away.
• Skip some entries due to various reasons
  • Too many (more than 50) properties to add. Because I'm hesitant to spam Wikidata with 100 i18n packages in each repository for e.g. firefox and libreoffice. Feed free to contact me if you think this is OK, also it may be tuned from the command line with --max-entries argument.
  • Multiple Wikidata entries for a single Repology project. This is likely an error, no such cases ATOW.

As you can see, it adds missing Arch, FreeBSD, Gentoo and AUR package properties for slf4j, nagios and pymol, skips libreoffice due to a lot of packages, and complains on texlive-core specified in Wikidata as Arch package for texlive, but absent in Repology (and here it's Repology problem as texlive project is not fully merged there yet).

Blacklist

You may exclude some Repology projects or Wikidata items from processing through blacklist.txt file. The most common reasons for this is postponing some projects or handling discrepancies between Repology and Wikidata (for example, when a project and its fork are single entity in one place, but split in another). Hopefully the blacklist would shrink with time, as discrepancies may be solved from both Repology and Wikidata sides after some analysis.
