Hi all,
we are happy to announce the release of DBpedia version 3.2.
The new knowledge base has been extracted from the October 2008 Wikipedia
dumps. Compared to the last release, the new knowledge base provides three
mayor improvements:

Hi Andreas,
we for sure want to do this, but also did not want to postpone the DBpedia
3.2 release any further.
So be ensured that the upcoming public user interface for defining the

classes and properties and that

Thanks Chris and team for all your hard work getting this done. I do,
however, have a few comments regarding the OWL ontology. I think in

Hi Jens,
We specified the domains and ranges as disjunctions of classes (not
intersection). See the W3C specification of owl:unionOf [1].
The version I downloaded from http://wiki.dbpedia.org/Downloads32 had all the
range restrictions as owl:intersectionOf. Or rather properties like

John's comment relates to (at least) the axioms on publisher:

In the future, there will be a user interface for specifying

the schema will increase over time.

Very nicely put, Richard.
We are opening up the discussion here of when to define one's own and when to
(re-)use from elsewhere.
I am a bit uncomfortable with the idea of you should use a:b from c and d:e
from f and g:h from i...
It makes for a fragmented view of my data, and might encourage me
I second Hugh and Richard's point.
I think the job the DBPedia people are doing in trying to corral Wikipedia into
order is an outstanding contribution. And it's obviously hard. Uniting the
various forms of birth date and birth place for example really increases the
value of the dataset. And
Hi Hugh and Richard,
interesting discussion indeed.
I think that the basic idea of the Semantic Web is that you reuse existing
terms or at least provide mappings from your terms to existing ones.
As DBpedia is often used as an interlinking hub between different datasets

its content more accessible and (re)usable.
That's it.
