Good morning, Stas Malyshev & Magnus Manske ,
Thanks all for your prompt response and for sending me the related site resources. I have been reviewing the references sent and am very content with this path seeking experience. I am looking forward to the Geo support that will be added with the next Blazegraph update, AFAIK. Although, I know not much about how this update will facilitate for the retrieval of Geo attributes ( e.g., bounding coordinates, shapefile data, Woe id etc .) Either way, very interesting!, Great Thanks, Jorge Hernandez On Sat, Feb 20, 2016 at 4:00 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.
