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 DBpedia4. 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.

Have a look at<http://musicbrainz.org/>, 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.
