There seems to be a clear inconsistency here... No. Example a) might looks like this: ApiDocumentation: ForumPost supportedOperation x, y, does *not* include DELETE /posts/a operation z, *not* a DELETE No DELETE in the representation of /posts/a and the ApiDocumentation also "doesn't tell me otherwise", i.e., also doesn't include a DELETE. Example b) might look like this ApiDocumentation: ForumPost supportedOperation x, y, does *not* include DELETE /posts/b operation x (again, *not* a DELETE) The representation of /posts/b includes some (x) but not all (y is missing) operations know to be supported by instance of the class ForumPost. Thus, /posts/a has the following operations: x, y, z /posts/b has the following operations: x, y Where do you see "the clear inconsistency" Pat? -- Markus Lanthaler @markuslanthaler
