Hi Peter,
short answer: The feature is in the dev pipeline:
First, we need to consolidate release quality (at the moment we have
duplicates, some RDF errors and unsorted dumps, some metadata UTF-8
issues), I guess this will get better in 4 -8 weeks or 2 releases.
At the moment you can already query some provenance info:
http://global.dbpedia.org/id/57Lcb or
http://global.dbpedia.org/?s=http://dbpedia.org/resource/Ronald_Reagan
or via the http://dev.dbpedia.org/Global%20IRI%20Resolution%20Service
see Reagan here:
http://vmdbpedia.informatik.uni-leipzig.de:5000/lookup/?uri=http://dbpedia.org/resource/Ronald_Reagan
will give you access to the entity and then you can search for properties:
dbo:spouse is extracted from en, fr and wikidata
http://global.dbpedia.org/?s=http://dbpedia.org/resource/Ronald_Reagan&p=http://dbpedia.org/ontology/spouse
dbr:spouse is not yet loaded.
We are working on extending the provenance information to pinpoint the
exact dataset file as well (now only linked data links are given on a
coarse level)
Once this is done it will:
- be available as JSON as per provenance-data-json.bz2 on
http://downloads.dbpedia.org/repo/dev/fusion/
- viewable via the GUI above
- from the DBpedia HTML interface, we will link to the provenance view
Note that we will also allow outside datasets to be linked and
advertised soon (January), see the prototype here:

Cheers,
Sebastian

A big hurrah about the new DBpedia releases, as announced in

Is there documentation on what shows up where in
http://downloads.dbpedia.org/repo/lts/
For example, where can I find triples that look like
dbr:Ronald_Reagan dbo:spouse dbr:Nancy_Reagan .
Thanks,
peter
