Kingsley,
when I open your link [1] I see the statements
http://opengraphprotocol.org/schema/Actor owl:equivalentClass
http://dbpedia.org/resource/Actor
http://dbpedia.org/resource/Actor owl:sameAs
http://dbpedia.org/ontology/Actor
I think it'd be better to solve the existing issues with the data in DBpedia
before... adding arbitrary new ones.
Georgi,
The context of my demo is this:
1. Yesterday, the opengraph folks were gently introduced to the power of
Linked Data via schema mapping
2. The people who participated in the mapping smartly added an
owl:equivalentClass mapping that hooked into the DBpedia ontology
3. I then put out Web page URL to demonstrate expansive effect of this
single TBox assertion (Fred Giasson used to call this Domain Explosion) .
That's it.
Nothing to do with other imperfections that may exist in DBpedia or the
DBpedia ontology. If anything, should you follow-your-nose, my demo
takes you to Yago, OpenCyc and UMBEL, at each stop giving the "bholder"
an option to explore the underlying ABox data via different "Context
Lenses".
Anyway, to your specific point:
Fixing DBpedia and mapping to DBpedia are tasks that can occur in parallel.
Note (or remember): the crosslinks exist in a separate Named Graph from
the main DBpedia Graph (go SPARQL against the DBpedia graph and you
won't find this data). My page is what brings the two graphs together :-)

Subject: [Dbpedia-discussion] TBox Meshup: opengraph meets dbpedia and
beyond
All,
One of the cool things that came out of yesterday's opengraph schema
enhancements was the mapping to DBpedia's ontology. Naturally, the
effects of this aren't obvious if you can't even view the ontology
etc..
Here is a link that shows the effect of TBox meshups:
BTW -- do note that the UMBEL project [2] was always about this kind of
meshup. Now if you follow my TBox meshup, you will note that the
DBpedia
and UMBEL ontologies aren't directly connected, but once you get to
OpenCyc (by following-your-nose) the connection manifests.
Conclusion:
As the lights really begin to brighten re. Linked Data, you will begin
to see a lot more of what's be talked about in the past but not fully
comprehended or appreciated. For instance, these mapper
schemas/ontologies lay the foundation for optional "context rules" that
make Linked Data meshes much more coherent and navigable (i.e., adding
CLASSiness [3])

3. http://bit.ly/dk0yvu -- old post about CLASSiness shot to DBpedia
(note: the queries reflect older DBpedia incarnations).
