Subject: RE: [xri] XRI discovery -vs- resolution
I'm torn. I like discovery, it sounds cleaner and is easier to remember. OTH, isn't it different? You resolve a single address to a resource, your discover resources by discovering their addresses (each of which you can then resolve). Discovery, as I'm using it above, seems missing from XRI specs. In my own backyard I am using a simple home-grown XRI discovery using variables and or convention: (1) A discovery result in XRDS form is one which only contains nested XRDS elements, each of which contains resolution of a discovered XRI. Alternative form is URI-list in which case each URI in list is an HXRI representing one of the discovered resources (2) XRIs of the XDI form xri:authsegmenthere/sometype.A.here each return an a discovery result of all locally known XRIs of the form xri:authsegmenthere/sometype.A.here/some.instance.id.here, uses xdi discovery service (3) XRIs of the form xri:xri.containing.XPL (for example xri://@x*($(member/+Person))*blog) return a discovery result of all locally known XRIs that match the expression (currently I'm working on conditions, but only vars working), for example xri://@x*Alice*blog, xri://@x*Bob*blog, xri://@x*Sue*blog. Note that for an XRDS discovery result each xrds representing a result would have an attribute (http://x.com/xpl/0.7/binding):member with the appropriate attribute value (Alice, Bob, or Sue). Once I have a reference impl working I plan on pulling my home-grown discovery mechanism into a proposal doc and submitting to XRI TC. The domain name and @-authority above for XPL are not fixed yet, hence x, but they will be when I submit my doc to the TC. FYI, I am cognizant of the security and privacy implications in this kind of discovery mechanism, and have policy-enabled access control (eventually will move to XDI link contracts).
