Playing with wdtaxonomy

Those queries from my last blog entry? Never mind!

After I wrote about Extracting RDF data models from Wikidata in my blog last month, Ettore Rizza suggested that I check out wdtaxonomy, which extracts taxonomies from Wikidata by retrieving the kinds of data that my blog entry’s sample queries retrieved, and it then displays the results as a tree. After playing with it, I’m tempted to tell everyone who read that blog entry to ignore the example queries I included, because you can learn a lot more from wdtaxonomy.

Extracting RDF data models from Wikidata

That's "models", plural.

Some people complain when an RDF dataset lacks a documented data model. A great thing about RDF and SPARQL is that if you want to know what kind of modeling might have been done for a dataset, you just look, even if they’re using non-(W3C-)standard modeling structures. They’re still using triples, so you look at the triples.
