You'll probably want to bash me, Ralf, but I have always favoured your initial suggestion ("Another proposal") :-). Main reason is that without a second call, as in the case with this new proposal, I can get the type information of both the link and target resource and _also_ the attributes of that link, in the examples shown, a specialized Link. Where one aspect of confusion or debate arises with your initial suggestion is the idea that if a model entity has a Category associated with it, the entity must then be a Resource. I don't quite see it this way. Rather, I see the addition of a Category to any (R)resource (except Category itself, that's non-sensical) as a means of signaling type information. Andy PS: I hope I'm not repeating an earlier argument of someone elses. -----Original Message----- From: occi-wg-bounces@ogf.org [mailto:occi-wg-bounces@ogf.org] On Behalf Of Ralf Nyren Sent: Tuesday, August 17, 2010 5:50 PM To: occi-wg@ogf.org Subject: [occi-wg] Revisiting Fat Links Hi all, After more discussions and writing a sample implementation of the Link as a resource concept I have come to realize its advantages. I do however still believe that Fat Links are necessary to be able to model all relevant use cases. Alexander pointed out that compared to his Thin Link proposal Fat Links would not integrate in a sufficiently clean way with the OCCI core model. In an attempt to address some of these concerns I have added a new section called "Revisiting Fat Links" to the Link & Linking page [1]. The changes from the previous Fat Links proposal are: - Link specialization is realized through the use of additional categories, i.e. the same way OCCI Resource resources are extended so is also the Link resource extended. - The class attribute is _not_ used to delegate the Link type. It merely says that the link MAY be specialized. It is an indication to the client to request Link details. - The rel attribute is used to delegate the type of the Link target, i.e. as suggested by the Web Linking draft. Comments welcome. regards, Ralf [1] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Link _______________________________________________ occi-wg mailing list occi-wg@ogf.org http://www.ogf.org/mailman/listinfo/occi-wg ------------------------------------------------------------- Intel Ireland Limited (Branch) Collinstown Industrial Park, Leixlip, County Kildare, Ireland Registered Number: E902934 This e-mail and any attachments may contain confidential material for the sole use of the intended recipient(s).
