I tried to add RDF-Files over the import function of POWL and there where blank fields in the database, where there should be blank nodes.

Seebi double checked and it is a bug in the RAP-Api.

The problem occured with complex owl:Class definitions especially if they use lists.

Here are some examples:

    Sorry, i tried to upload several files, but the bug submitted itself after the first file,
    so I made a zip archive.

    It contains three RDFs and the according resulting table entries.

    Missing value is in all cases the blank node of the beginning of a Collection:
    (I changed it to Qnames for better reading, see the pdfs in the zip for complete tables)

    http://www.test.de/Collection rdfs:type owl:unionOf
    ???? rdfs:first http://www.test.de/test#u1
    ???? rdfs:rest node2
    node2 rdfs:first http://www.test.de/test#u2
    node2 rdfs:rest rdfs:nil
    ???? rdfs:first http://www.test.de/Collection
    ???? rdfs:rest rdfs:nil
