RE: event semantics?

Sam,
No, these are independent submissions. Both address the nature of
process. However, I think the difference is that SWSF is an
ontology-centric approach (activities, occurrences, timepoints and
objects are ontologically distinct entities) capturing the semantics of
process as a set of constraints. This supports the interchange and
verification of (partial) process descriptions. As I understand it, WSMO
uses abstract state machines which are more algorithmic in nature, as
required to support mediation.
