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."     -Gabe
 
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.
