Hi George, Here is something that might work, please give it a try.
1. Leave all the @prefix declarations pointing to the old namespace, both in the mapping file and in the assembler file: http://www.wiwiss.fu-berlin.de/suhl/bizer/D2RQ/0.1# 2. In the assembler file, find the following line: <> ja:imports d2rq: . and change it to: <> ja:imports <http://d2rq.org/terms/d2rq> . If it works, please let me know and I’ll update that information in the documentation.
