Re: [Anima] I-D Action: draft-ietf-anima-grasp-api-06.txt

Hi,

This version was updated following the WG Last Call, mainly to handle the comments in Laurent's careful review. In my opinion the changes are all of an editorial nature, including useful clarifications; there is no change whatever to the technical details of the API. I will just mention a few points of interest:

(1) Laurent suggested adding definitions for "idempotent", "atomic access", and "operating system locks". We expanded the text slightly for the first two, and removed the reference to locks.

(2) "multi-threading, an event loop structure using polling, and an event loop structure using callback functions." Laurent suggested adding a reference for this, but we didn't find a good reference such as a standard textbook or a review article. Suggestions welcome.

(3) Laurent said "Wherever a "timeout" parameter appears, it is an integer expressed in milliseconds. - why specify the unit in an informational document?)". We think it's necessary to specify the unit, since portable apps need portable units.

(4) Laurent said "What is the reasoning for the default support of discovery for objectives?
there may be situation where the exposure of the objectives should be controlled." Our response is that GRASP has no authorization model; we trust an ASA because it has access to the ACP. This aspect would change if we added an authorization model to GRASP, so it's not an API problem today. (It is a topic for future work in ANIMA!)
