Subject: Re: Special case objectType's
Using something like id:@friends would work conceptually, but it falls down a bit when attempting to reference specific subgroups and there's the restriction that id MUST be an absolute IRI, requiring us to come up with some artificial uri scheme for these that just isn't necessary. Truthfully, I don't see the @values as being out of place in the object type.

Seems weird to overload objectType for this. Feels more natural to define conventions for the "id" property since it seems like you are trying to identify specific objects rather than classes of objects.

Within poco and OpenSocial there exist a number of special case
identifiers such as @me, @public, @all, @viewer, @owner, etc that
represent a variety of specific, well-known types of objects. What
currently does not exist, however, is a standardized way of
representing those within an Activity Stream document.. for instance,
if I wanted to indicate that the audience of a particular event is
@public... What I propose is that for these special case types of
objects, we utilize the convention of specifying the @value as the
objectType, for instance...
{
"to":[{"objectType":"@public"}],
"cc":[{"objectType":"@network"}]
}
To identify subsets of these, we can differentiate based on the "id"
property.. for instance, a service that offers identified groups of
friends (e.g. Google+ circles,etc), we could use the following
convention:
{"objectType":"@friends"}<== identifying ALL of my friends
{"objectType":"@friends","id":"urn:whatever:colleagues"}<==
references the subset of friends identified as "colleagues"
{"objectType":"@friends","id":"urn:whatever:family"}<== references
the subset of friends identified as "family" ,
... and so forth
Thoughts?
