[WIPR] Connect WikiProjects in the Tools section on relevant Item pages using properties
Open, Needs TriagePublic
Actions

Description

As a wikidata editor I want to know if an Item is related to a wikiproject so that I can connect with other editors who share a common interest.

Using Properties on Items on Wikidata we will link to:

We will link to WikiProject Music for Items that use the following properties:

We will link to WikiProject Medicine for Items that use the following properties:

We will link to WikiProject Datasets for Items that use the following properties:

We will link to Wikiproject sum of all paintings for Items that use the following properties:

We will link to WikiProject elections for Items that use the following properties

The link should be displayed in the tools section following the design

Note: there is concern that this will impact the rendering time of all Item pages, so we will need to track the impact of the changes

Acceptance Criteria

  • On Wikidata, Items that have statements that use Properties related to the various WikiProjects display a link to the respective WikiProject following the default of same-window navigation
  • This link is included in the tools section of the Item page, following the design. Making sure to be enabled under a "feature-flag".
  • Items that do not have any statements that use any of the relevant properties should show no WikiProject section or link
  • All links are tracked using T421856
  • Monitor rendering time before and after implementation

Blocked by T427804: [WIPR] Allow for translations of Wikiproject names as what is included in the config depends on the translation

Making sure to be enabled under a "feature-flag".

I’m not quite sure what this entails, to be honest. As far as I can tell, the only thing that’s left to do in this task is the configuration itself; the code in Wikibase has already been taken care of (including by T427804, which is mostly done and will roll out with the train next week – the config change would have to wait for that). And the configuration itself is the feature flag – so the moment we deploy the config, the links should be live, and if we revert the config then they’ll be gone again.

Are we planning to deploy this on a specific date? Or just whenever we’re ready?

We will link to WikiProject Medicine for Items that use the following properties:

May I suggest that we also exclude has cause (P828)? A great many things have causes :)

Similarly, I’m not sure if everything with a chemical formula (P274) should be counted as in that project’s scope.

We will link to WikiProject Datasets for Items that use the following properties:

I’m not sure about some of these properties either:

I am happy to exclude all the properties you mentioned.

And regarding the release, it would be deployed ideally as soon as we are ready. I'll ask Mohammed to put together an announcement and we can send it out alongside the update

Testing of the above config change on mw-experimental shows that medical condition is apparently not listed as a WikiProject Medicine property ^^

Apart from that, the config change seems to work as expected, as far as I can tell from some random items.

The acceptance criteria mention "Monitor rendering time before and after implementation" - what is the plan for that here?

I was thinking of MediaWiki Engineering/Guides/Measure backend performance § Benchmarking and load testing in production – after looking into it this morning, that turned out rather more complicated than I anticipated, but I now think I have something that works.

Without the change (the curl is meant to warm up the server a little bit, and in particular ensure that the page is in the parser cache):

That sure looks like a measurable difference of at least 10 ms if not more :/

I did another round of performance testing and put the results on a wiki page, which has more formatting options (especially mw-collapsible). The overall result is similar: a performance cost of ca. 20–40 ms (somewhat more for the larger item, albeit taking up a smaller percentage of the total request time there).
