Subject: RE: [xri] Compromise Conceptualization Towards CD-02
"Here's where we get into trouble -
what is meant by "the authority". If xri://@foo*bar is an authority, then its
not a dog. Last time I checked, dogs couldn't answer XRI subsegment
resolution requests. But we can just sort of ignore that by saying that the
result of resolution describes the dog and services on the network that act as a
proxy for the dog on the network. In the new conceptualization,
we are saying that resolution of @foo*bar gets back both descriptions of the
resource and network services offered on behalf of (or "relative to"?) that
dog."

I've always understood the authority segment to represent exactly
that: the XRI of the authority over a resource's data. For example if the
American Kennel Club was an authority on its dog data, and data about registered
dogs in particular: xri:@akc*dogs*registered would resolved to a resource
describing the authority, i.e. an XRID, xri:@akc*dogs*registered/dog/somedogid
would refer to a specific dog, i.e. return a document of type Dog. So how do we
describe @akc*dogs*registered? I'd suggest allowing for one or both of the
following:
. Either extend XRID schema such that RDF and/or XDI elements
can be embedded with the XRID
. Or standardize a $ word path s.t. xri:@akc*dogs*registered is the
authority, xri:@akc*dogs*registered/($about) that returns a metadata document in
a format specified using the $ format specification scheme, and XDI as as the
default if no metadata format specified.
I chose /$about rather than *($about) as *($about) seems to imply
that authority over metadata about a particular authority A could be delegated
to a authority B and it seemed a good idea that authority A is always the
authority of it's own metadata, but I'd be interested to hear which those with
more XRI experience think is better.
