Hello All,

WikiData URIs inside DBpedia is under a new name space called "wikidata" on
the form http://wikidata.dbpedia.org/resource/Q1293045

the sameas dump contains mappings between URIs of Wikidata entities inside
DBpedia (the one described above) and DBpedia entities.

i guess what we need now is to map between the original WikiData URIs and
their URIs we use in DBpedia under the new namespace , for example :

<http://wikidata.dbpedia.org/resource/Q1293045> owl:sameAs
<http://wikidata.org/entity/Q1293045>
Why don't you just use the WIkidata URI?

Correct!

These have to be Wikidata Linked Data URIs, as per my earlier post.

Cheers,

i was intending to add this in the next release, but if it's needed for
loading up the data i guess we can let it run before that.

thanks
Regards

Hi Hady and all,

good stuff!

After a few changes [1][2][3][4], the mappings wiki now renders http
links to property pages on www.wikidata.org for equivalent wikidata
properties (and to schema.org and bibo as well).

Cheers,
Christopher

Great!

Is there new URL for a revised dump? Or is the revised dump accessible
using
the existing dump URL?
which dump?

Specifically, the following:

1.

http://wiktionary.dbpedia.org/wikidata_tmp/wikidatawiki-20130817-wikidata-sameas.ttl.gz
2.

http://wiktionary.dbpedia.org/wikidata_tmp/wikidatawiki-20130817-wikidata-labels.ttl.gz
3.

http://wiktionary.dbpedia.org/wikidata_tmp/wikidatawiki-20130817-wikidata.ttl.gz
.

We loaded these into our LOD cloud cache only to find out that the
subject
URIs for the sameAs relations where incorrect i.e., they don't resolve.

For example, the dataset had
<http://wikidata.dbpedia.org/resource/Q1293045>
when it should be <http://www.wikidata.org/entity/Q1293045> .
I don't know about these. @Hady @Sebastian, can you help?

Hello All,

as a part of GSoC2013 project , integrating WikiData inside DBpedia
,
we
are
in the phase of mapping Wikidata properties to DBpedia ones .
this is important because once all mappings are done we can extract
a
complete DBpedia facts dump with DBpedia properties from the
Wikidata
one

So, we need a little help from the community to in mapping of
Wikidata
properties , there's around 544 Wikdata properties in use , that
needs
mapping
you can check most important ones in that Google spreadsheet to
start
with
,also properties that weren't mapped yet.

in this wikipage there are detailed steps to add the mappings.

thanks
Regards
