Following up on the telecon, I started a page for the BC audit.

As I understand it, any BC issues should go on Tracker. Discussion  
can take place on the Wiki page or on list.

Some of the documents make BC claims like:

"""" Every OWL 1.1 ontology can be serialized in RDF, so every OWL  
1.1 ontology in RDF is a valid OWL Full ontology. The RDF syntax of  
OWL 1.1 is backwards-compatible with OWL DL, this is, every OWL DL  
ontology in RDF is a valid OWL 1.1 ontology."""

It would be good to verify these.

There are some clear non-BC points. For example, the Functional  
Syntax is not BC with the Abstract Syntax, and quite radically so.  
There is a rationale section:

And a paper:

Plus the papers discussing the OWL API at OWLED 2006 and 2007 mention  
the advantages of the new Functional Syntax.

So, the current documents reflect a view on essential vs.  
inessential, which I think it is pretty intuitive. I've not heard  
anyone yet claim that that view got it objectionable wrong, but I  
hesitate to predict whether this shall continue. If you object to the  
lack of BC between the functional and abstract syntax, please say so.
