Re: CfC: Resolution Annotation Protocol to make JSON-LD default returned if no HTTP Accept request header (deadline 24 June 2015)

Hey, folks–

If everyone else is satisfied that we can override a SHOULD in LDP with 
a MUST in Annotation Protocol, that's good enough for me.


I proposed an erratum on LDP simply because it seemed the easiest way to 
resolve the issue (for the LDP spec); errata don't have to be errors, 
they can also be issued because ongoing implementation experience 
differs from the Rec; if it turns out we get more LDP servers defaulting 
to JSON-LD than turtle, the spec would more accurately reflect interop 
if it we to change that statement. Errata can introduce changes that 
affect conformance [1], if warranted by the ecosystem.

If there are major substantive changes needed for LDP, then probably a 
v2 is needed, which would require the re-formation of a chartered WG; 
otherwise, a 2nd edition can be made, which can be done by the W3C Team.

But all this is administrivia that will only be relevant if we decide in 
the future that we need to update LDP. For now, it seems that we have 
consensus that we can require JSON-LD as the default return format for 
Annotation Protocol without causing a conflict with LDP.
