Subject: Re: [soa-rm-ra] OASIS' Ref Ontology for SOA
I noticed the SEE starting up, and thought it was more related to BPEL, WSBPEL etc. Wrong. Dave clued me about it this morning following Jeff's post, which I hadn't looked at up til then. Since it directly relates to the EM Reference Information Model SC I chair, and the EDXL-RIM work we're doing there, I'm in the middle of reading it through and making sure I download and understand their references, which include some highly structured first order logic, specifically SWSO, but SWSL, too, which this document only touches on. They're specifically distinguishing themselves from our work, as Danny noted. They are apparently confining themselves to UML for illustrative purposes and WSML for formal representation, and I'm not fluent in that language, sigh. More homework, oh goody! I guess I'll find out if my tools can accept it as input. While this document is not huge or a conceptually big stretch, the implications may well be. Because it places a mediator square in the middle, I understand Dave's attraction and mine, but WSML has 4 specs and the abstract syntax says that a WSML Description is a 5-tuple and actually makes good sense to me, but... I guess the big question I have is who are the businesses are that are going to use this? I would really hate to try to explain this to a manager... or even a CIO.
