Bernard,

As you can see from the announcement, this is a little transition period 
between the combination of DBpedia datasets and Linked Data deployment, 
via the DBpedia endpoint.

This is simply a case of transition. The problem will be fixed, 
promptly. The URIs below should aid tracking and problem comprehension. 
Also, these URIs won't change following resolution of the TCN issues. 
Might even be fixed before you read this response.

[1] http://dbpedia.org/ontology/TimePeriod
[2] http://linkeddata.uriburner.com/c/9CU7GSFP -- the problem (which is 
basically TCN and legacy issues with text/rdf+n3 and text/turtle).
