Greetings, Very interesting topic,
Would love to learn more about geo coding with Wikidata, or maybe even about spatial modeling or creating significant improvements into desired gazeteers &/or geodatabases. Ofcourse, I am not familiar with much of the .rdf output, but maybe we can talk about those summarized efforts towards retreiving spatial attributes using the Wikidata API >? (SPRQL). -Jorge Hernandez On Fri, Apr 8, 2016 at 10:34 AM, <[email protected]> wrote: > Send Wikidata-tech mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.wikimedia.org/mailman/listinfo/wikidata-tech > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Wikidata-tech digest..." > > > Today's Topics: > > 1.
