Basically: Use Freebase to author ontologies / classes / etc, and rip out the results as owl. In theory it wouldn't be too tricky to 1. Port it to Acre 2. Integrate some of the owl:sameAs stuff you've been doing I haven't really touched it since. For the converting date formats between models, I'd reach for tools like GRDDL/XSLT + a scripting language, but those aren't too applicable for you.
