Hey folks :)
We just enabled statements on properties. You can for example use this to:
* describe mappings to other projects' vocabularies
* indicate constraints for the usage of this property (currently
stored in templates on the talk page of the property)
* store information about where this property is used in other
projects to make sure they can be notified when major changes are made
to how the property is used
* provide links to extensive documentation about and showcases for the
usage of this property
* store patterns for how an identifier should be expanded to form a proper URL
* ...
Some notes:
* You can't yet make statements linking to other properties to for
example indicate that property X is the inverse of property Y. We are
adding a new datatype for that. It'll come soon. The ticket for that
is
https://phabricator.wikimedia.org/T75302
* Constraint violation reports currently don't take these statements
into account. They will continue to use the templates on the
property's talk page. A team of students is currently working on
overhauling the whole constraint system. It'll take them a while still
though.
Unrelated but also important for you to know: If a page is deleted on
Wikipedia/Commons/... that has a sitelink in an item on Wikidata that
link will be removed automatically now.
Cheers
Lydia
