Thanks for your answers. I like RDFIO's behavior of just importing the RDF, without adding SMW specific elements (e.g. categories, redirects etc.). My goal is it to import any RDF (RDF(S), OWL) and then run through it with a bot to set up the look and feel.
However, I see some problems with RDFIO: - How are the property types of data type properties set? Should this not be done generic, e.g. as specific as possible, as general as needed? - As I see it, SMW RDF export and RDFIO SPARQL endpoint give different outputs. Should they not provide the same information? - What happens if imported information already is available in the wiki? Do you really think it should be duplicated? Also, I am not quite sure, whether RDFIO properly checks if pages already represent URIs and can be just updated by the imported RDF. - Apparently, it is not that robust: When I run RDFIO it sometimes gave me an error because of inappropriate wiki titles. Also for bigger RDF it reached max execution time and quit (although I set a higher one in php.ini).

I agree, and the former is really a prerequisite of the latter. Ideally, SMW could thus obtain access to external Linked Data (cached locally for query answering). Ways of dynamically locating and pulling such data have already been explored in the SMW-based ShortiPedia prototype (shortipedia.org). In any case (to answer Benedikt's initial email), the old vocabulary import functionality and the equivalent URI method both affect the RDF export only, and do not contribute to the data as viewed in SMW (e.g. via queries). This whole aspect of SMW needs to be rethought.
