Add Wikibase and WikibaseLexeme
With the latest changes of T291617, this should Just Work™ on the master branch (though not on any existing REL1_* branches). It’ll result in a repo+client wiki with Items, Properties and Lexemes in dedicated namespaces (120, 122 and 146 respectively).
Bug: T372960
Note: I have no idea how to test this. I hope one of the Patch Demo / Catalyst maintainers has a test system :)
(If you want to test whether Wikibase actually works on the wiki once it’s been created, you could try going to Special:NewItem
and creating an item. If you also want to test repo-client interaction, create a property on Special:NewProperty
(datatype String is easiest), use that to create a statement on the item, then on the item’s talk page add the wikitext {{#property:P1|from=Q1}}
and see if it shows the statement value.)
