Oops ! one more thing about the mappings that I forgot to mention to all. Which is very important. http://pending.schema.org That is were schema.org holds its work-in-progress or review of a draft idea for Classes (Types) and Properties. We have already mapped several of them that are currently

Nice Kingsley! Great work. So nowthe bad news and where we need further help still :) I do want to let everyone know however that within Classes and Properties...there are a slight few mappings that were taken as an opinionated view I.E. they may slightly conflict with other views of the ma

Kingsley, You might ask others on the list who could help more with providing the WD - Schema.org mappings or get them into a format that you want...or an RDF dump file. I just don't have the knowledge to assist you with that via SPARQL. (i.e., I am not a SPARQL guru) -Thad

Thanks Andrew but I know and see the pitfalls. The use case is only 1 level deep and to be treated not as a Category but instead as simply something "Related" or "Relative" to the topic. Keeping within those 2 constraints from my tests seems to work reasonably well. Beyond those constraints... I a

Re: [Wikidata] Help with SPARQL or API or something to get subcategories

Hi Thad, One quick red flag - I'm not sure how familiar you are with the category system, but automatically parsing it without sanity-checking can very quickly lead you into a minefield. There are a substantial number of category trees which seem reasonable at first, but rapidly go in unexpected d

Re: [Wikidata] Help with SPARQL or API or something to get subcategories

Hoi, Magnus does use subcategories extensively in his tools. It is not WDQS but it is data. Be warned, many of the "lists" and "categories" in Wikidata are not only this but are reused for other purposes. Thanks, GerardM On 6 October 2016 at 20:57, Thad Guidry wrote: > Hello team :) > > So

Re: [Wikidata] Help with SPARQL or API or something to get subcategories

DBpedia has the category data in RDF. The last release of DBpedia also included Wikidata - it should be possible to query the combined dataset there. On Thu, Oct 6, 2016, 19:47 Thad Guidry wrote: > Cool. Yeap, you got the idea now. > > OK, We'll stay tuned for a future new Service ! > > Schema.

Re: [Wikidata] Help with SPARQL or API or something to get subcategories

Thanks Stas, So, hmm...we'd have to build our own parser or something is what your saying ? Because Wikidata doesn't have those kinds of connections in its graph and also doesn't have a SPARQL service yet against the Wikipedia API:Categorymembers https://www.mediawiki.org/wiki/API:Categorymembers
