Hi again, Reading the specs I cannot quite figure out how to remove an association between one resource and another. As far as I understand PUT can be used to add a new or change an existing association, i.e. using Link headers. But how to remove an association? Reading the Wiki [1] I found some new text which indicates that DELETE somehow can be used to remove associations as well as resources. The described semantics seemed to be rather complicated. You have probably thought a lot about this already but from my point of view any operation which irreversibly deletes/destroys a resource should have as simple semantics as possible. Using DELETE to remove associations seem dangerous to me. What are your thoughts on this matter? regards, Ralf [1] http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/CoreAndModels...
