Hi all,

The Wikidata <-> DBpedia mapping effort started last year with a manual effort lead by Hady El Hasar. See [1] for a full list of existing mappings.
This year, Marco is supervising a GSoC student to generate mappings automatically, that gdoc is their current progress.

@Daniel, I remember you already had the mappings wiki in mind 2 years ago when you presented Wikidata in the MLODE 2012 / DBpedia roadmap session
But it was too early for Wikidata back then, maybe now is the time to look closer at this.

We have our 2nd DBpedia Community meeting in Leipzig in 2 weeks

We'd be glad to have Wikidata devs and community members around and discuss similar ideas.

btw, Wikidata was present in our 1st community meeting in Amsterdam with Gerard Meijssen

Hi everyone,

The following spreadsheet contains the latest DBpedia <-> Wikidata mapping effort both for properties and classes (cf. the 2 sheets) made by the GSoC student so far.


Since I am his main mentor, feel free to ask me further details.
Hope this helps!

    Even if it proves too tricky to map individual template parameters

    of an item
    based on the templates the respective wikipedia page contains. We should
    definitely map dpedia classes to wikidata items.

Sergey Skovorodkin is working on a dbpedia<->wikidata mapping as a GsoC
for DBpedia this year

I'm CCing him to see if he can report the status or if he might need
help with our properties, maybe we are missing some or need to clarify
some others. Sometimes we are using qualifiers to extend properties
instead of creating new ones.
