All, As of my ACTION-72 [1] I have now set up the Test Cases as discussed at the Barcelona F2F, see [2] for an overview and motivation and [3] for the actual test cases (MF-TC), where we gonna review and approve them (for now). I encountered the following issues while implementing this: + While it is straight-forward to come up with empty MF, I did not find a way to express the entire resource given that a namesegment or axissegment is present. Thoughts anyone? + TC0008, though desirable, will currently fail due to our MF Grammar + When implementing TC0009 I found this hard to express without saying something about the media type (that is, IMO we need an additional field that defines the targeted media type). As you know, the semantics of the URI fragment are media type dependent, hence this shouldn't take us any wonder ;) + CLASS1 and CLASS2 TC are HTTP-specific and can only be implemented once we have agreed on the actual network communications (which header fields, etc.) + There will certainly be other classes of TC that will address the RTSP case + In the overview [1] I sort of contemplate about a partitioning. The proposal currently on the table is to split into: 1. Client-side processing (see 'User Agent Media Fragment Resolution and Processing' [4]) 2. Network communication (for HTTP [5] and RTSP [6]) 3. Server-side processing My question now is: is this desirable, that is, keep 2. and 3. separate OR does the MF-WG rather think this should be merged?
