Yes, but owl:sameAs does not tamper with the original information. If
you disagree with a owl:sameAs statement you may remove that
particular statement and move on. That's not possible in TMDM, it
creates new topics and deletes others. Acc. to my understanding, a
processor which is OWL-aware does the same thing as TMRM: It provides
a merged view.

Best regards,
Lars
