Hoi,

Yes we could do that. What follows is that functionality of Wikidata is killed. Completely dead.

Also, this thread is about us being ready for what we could be, not for what we are. At that we are not as good as we could be. In your suggestions for inclusion we could have the "concept cloud" for Wikipedia articles defined by its wikilinks and define them in Wikidata. We don't. We could have a usable user interface like Reasonator. We don't.

The reason for this thread is what does it take for us to have a perfoming system because we don't. Our growth is less than what it could be. Our functionality is less that what it could be. At the same tme we are restricted it seems by annual budgets that do not take into account what functionality we provide and could provide. The notion that we should restrict our content for performance sake.. A rich organisation that is the Wikimedia Foundation. REALLY!!

Thanks,

GerardM

Hi Stas,

Many thanks for writing this down! It is very useful to have a clear
statement like this from the dev team.

Given the sustainability concerns that you mention, I think the way
forward for the community could be to hold a RFC to determine a stricter
admissibility criterion for scholarly articles.

It could be one of (or a boolean combination of) these:
- having a site link;
- being used as a reference for a statement on Wikidata;
- being cited in a sister project;
- being cited in a sister project using a template that fetches the
metadata from Wikidata such as {{cite Q}};
- being authored by someone with Wikipedia page about them;
- … any other criterion that comes to mind.

This way, the size of the corpus could be kept in control, and the
criterion could be loosened later if the scalability concerns are addressed.

Cheers,
Antonin
