Hi Kingsley,
Sorry for the newbie question but I don't really get what the page you
linked to should ideally output. Could you explain what is wrong in this
and what would be the good behavior for those 3 to collaborate smoothly?
(or link to any article explicating this)
Thanks in advance!
The page in question is the result of me using my knowledge of the data
sources to construct a specific kind relation for the underlying query
used by the DBMS engine. Basically, my approach isn't a pattern used by
a casual user. Anyway, I used this query to show that DBpedia, Wikidata,
and Freebase aren't cross-referencing they way they should. In a sense,
I see patterns that simply mangle what should be very straightforward
co-reference associations.
Issues:
1. Wikidata references Freebase
2. Freebase reciprocates
3. neither references DBpedia
4. DBpedia references both, but in the case of Wikidata it mints its own
URIs (due to issues with Wikidata's Linked Data URIs which may or may
not still exist).
Ultimately, I am also trying to show all the parties involved that
what's going on here doesn't really look good, and its going to be
easier to folks to see this, as the familiarization grows.

Hi Maxime!
Have a look
at<http://musicbrainz.org/>g/>, it uses structured data, is
freely
licensed, and they are very interested in integrating with Wikidata.
While Wikidata has finer granularity than Wikipedia, as far as I know
you would
not be able to include just any piece by any artist. MusicBrainz's
scope is
probably better suited for your project.
However, why only use one Database? Ideally, if there is a Wikidata
item about
some entry on MusicBrainz, these would be linked to each other using the
appropriate properties. So, you could search MusicBrains and include
information
from Wikidata if it is available (or vice versa).
Daniel,
In the light of your comments above, why can't Wikidata, Freebase, and
DBpedia cross-reference is a natural way. All I see right now are the
following, which I find suboptimal, for all the wrong reasons:
1. Wikidata cross references Freebase
2. Freebase cross references Wikidata
3. DBpedia cross references both, but makes bridge URIs in the DBpedia
namespace to achieve this, in regards to Wikidata.
1-3 isn't how this should be working out on the Web of Linked Data.

inability (for all the wrong reasons) for these projects to collaborate
effectively (just follow-your-nose by clicking any of the links in the
page to which this URI resolves).
