Hello everyone,

At the request of the OBO Operations Committee, Alan and I have created a classes-only variant of the OWL version of BFO. It contains all BFO 2 classes, with subClassOf and disjoint axioms plus all their annotations, but none of the object properties or logical axioms that use the object properties.

I apologize for the late notice: the plan is to announce the classes-only variant in tomorrow's OBO Foundry Community Outreach Forum. I wanted to share this work with the BFO-OWL list much earlier.

Alan has not yet done a final vetting, but I'd appreciate it if some of you could take a look and let me know if you see any problems.

- file:
- release notes:
- SVN:

Once again, I apologize for not sharing this work sooner.

Hello everyone,

We've changed the name of the classes-only variant and made a few small modifications:

If no major problems are reported, I will upgrade this release candidate to an official release on Tuesday (2014-05-27).

I seem to have a rare form of dyslexia that is specific to reading calendars...

Correction: I would like to make the release on Tuesday May 20 (2014-05-20).

Hi James,

That's wonderful news!

Once it is finally realized, I can upload the final version to Ontobee.

Also, we can update the BFO Converter tool to facilitate the conversion task for many ontologies:

Hi James,

Thanks a lot for making this classes-only BFO.

It looks good to me. 

Looking forward to seeing it officially released next Tuesday.

I'd like to chime in with the thanks. I think this will be a big help for coordinating term imports across ontologies. I have to do a release of BCO and PCO, but will wait until next week so I can use the new BFO file.
