parthood property chains incomplete #160

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
I am fairly sure the property chain declarations in the current BFO2 ontology 
are incomplete.

E.g. I think there should be

 * InverseOf(continuant-part-of-at-all-times) o has-continuant-part-at-some-time -> has-continuant-part-at-some-time

This is equivalent to writing

* has-continuant-part-at-all-times-that-part-exists o 
has-continuant-part-at-some-times -> has-continuant-part-at-some-times

I have not yet managed to generate a proof of this. My attempts so far are in 
the examples/property-chains/ directory.

It would be good if there were some kind of annotation assertion that allowed 
us to know if the OP was considered "done" - i.e. absence of an axiom is 
deliberate rather than error of omission.
