Subject: Re: [soa-rm] [For Issue #525] RE: [soa-rm] Groups - ProposedSOA-RM Relationship Names (SOA-RM Relationships Names.xls) uploaded
Yup, If we are going to provide relationship names to accommodate OWL, we need to be specific about which version of OWL we want to support or CAN support, given the abstract nature of the Reference Model. I would be happy with OWL DL, less happy with OWL Lite, and opposed to OWL Full. Going into the reasons is something we should take up in the f2f, because it is too lengthy for an email. However, I would prefer to put this on hold for a v2.0 which I suspect is almost unavoidable, though one hoped it would not be given sufficient abstraction. That said, I would select relationship names directly from the realm of RDF in general and RDF Schema in particular and, for me, OWL DL and not make up any new ones and I would start with extremely basic, very abstract, relationships and not use any terms that are open to interpretation. In other words, I would try to start with compliance with first-order logic. Going beyond basic classes and properties to subClassOf and subPropertyOf is about as far as I would go. Otherwise we open the door to a purely endless exercise in futility. It would take a lot of work and I don't think we have time for it in this version. This is probably not a good idea. I would prefer to see it be a separate specification, with its own set of requirements starting with mereology from general to specific, where you define things in the isPartOf relationship not the consistsOf relationship. The difference is that there are some accepted rules for mereology, and it works with formal logic. If we are going to accommodate OWL now we need to make sure we are not setting ourselves up for a bunch of logical contradictions by going full steam ahead before looking at the landscape and figuring out what kind of roadmap we need. I think the spreadsheet is a good way to get concepts out where you can look at them and pick away at them. I just don't think this is likely to get well baked enough to include in this round, and perhaps ought to be its own specification, a SOA ontology based on the RM. That would give us plenty of time to noodle and boil this down to workability.
