I don't think it's *much* more work, and I planned to do this work anyway :) Of course, it may happen that I am wrong about how much work it is, and then I might reconsider. > compute the number in a SPARQL query from the RDF.

Speaking of which, Blazegraph does have support for inferring data, but I don't want to open that particular can of worms just yet. > This leads to a slightly different perspective than the one you'd have > in T129046.

While in theory this is true, we don't have any process that allows us to do literally materialized views on current platform (there are named queries but that's not the same I think). Inference "kind of" might be that, but doing it that way probably would be very inefficient for this particular case. There are of course other ways to achieve the same, so I'll look into various options, but so far page props doesn't sound like that bad an idea, to me. -- Stas Malyshev smalys...@wikimedia.org _______________________________________________ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
