Is Wikidata again being held back by the SPARQL endpoint?   I thought that this had been resolved some time ago.


But are these triples redundant?  They might be redundant in the sense that someone who knows how sports teams, leagues, and seasons are put together would know where to look for the sport.  But this is putting a heavy bar on consumers of Wikidata, which in my opinion is not what Wikidata should be doing.  Instead Wikidata should be easy to use.  And it is entirely possible that these triples would not be redundant in all cases.

The Blazegraph Wikidata SPARQL endpoint (as it is a sadly abandoned codebase) already creaking at the seams, and struggling to keep up with the happily thriving growth of Wikidata.

In this situation it seems that adding redundant factoids into the database might not be the best use of constrained resources, for now at least.

More generally, where is any notion of inference in Wikidata defined?  


This is a good question, I’d love to know too. Maybe mapping the equivalent P:Whatevers to rdfs:subClassOf and rdf:type would be a start?

If they were in a form from which we could generate even just SPARQL CONSTRUCT queries, and perhaps populate an auxiliary dataset/database with the additional implied information.

There appear to be more problems with sports season.   For example, https://www.wikidata.org/wiki/Q1487136 doesn't appear to be linked to any league or cup.

Please do not do this,
What you are likely wanting to accomplish is relating a sports season to a category of sports and this is already done.  So the relationships are inferred.

Hi all,

Too many items on Wikidata still miss the basic statements. Perhaps we can focus together for a short period of time on a single subject to get this fixed.

For example: all items with instance of (P31) sports season should also have have sport (P641) as statement.

When I just ran a query I saw 24000 sports season items that are still missing sport (P641).


I already did a few myself but for the largest part help is needed. Who has ideas and can help getting this statement added to all the sports season items.

Thanks!

Romaine
