[occi-wg] Revisiting Fat Links

[Ralf Nyren]

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
