Store hints about entities in page_props table
Closed, ResolvedPublic


We need an easy way to list all empty entities, and perhaps also other "kinds" of entities, on special pages etc. This could easily be done via the page_props table, we just need to start using it. The page_props table is fed from the ParserOutput object (via LinksUpdate).

So, EntityContent::getParserOutput() should just add the desired info to the ParserOutput - it could be provided by a getPageProps() method or some such.

Initially supported "hints" or "kinds" could be:

  • empty: contains nothing at all
  • stub: consists only of label(s) and description(s) (and maybe also aliases).

There could be more, like "unlinked" for items with no sitelinks.

quick note: I think items should be marked as empty based on EntiyObject::isEmpty(). There should probably a similar EntiyObject::isStub() method, though that one would have to be overridden in the ItemObject subclass.

we could also put the number of sitelinks and claims into page_props, to make it easy to search for entities with no or many sitelinks/claims.

To allow efficient queries over page_props, it would need new indexes, see bug 58032.
