RE: [xri] resolution of an xri from browser, keep in browser or seperate?

["Drummond Reed" <drummond.reed@cordance.net>]

Brian,

I was in already in holiday mode when your original question came in, but I
just got back to reviewing it and I'd like to amplify on Gabe's response
with another view of how XRI-identified-resource interaction might work w/in
the browser (plus a key question it raises for XRI 2.0 resolution that I'm
sending in a separate email.)

[Disclaimer about the following - I'm co-chair of the OASIS XDI TC,
http://www.oasis-open.org/committees/xdi, so put all of this in that context
;-)]. 

The view is that the option Gabe articulates of having a standard way to get
more information about/interact with an XRI-identified resource could be SO
useful that this is one of the key goals of the OASIS XDI (XRI Data
Interchange) TC. The XDI TC is defining a way of using XRIs to identify and
exchange metadata and data related to an XRI-identified resource including,
if needed, negotiation of access to controlled resources using "link
contracts".

This means that the XDI perspective, Gabe's suggestion would be implemented
through another service associated with the XRI-identified resource
(probably called, naturally enough, "XDI" instead of "X2R".) The browser
plug-in that supported XDI would see if the XRI-identified resource
supported XDI, and if so, it could use XDI to request almost any kind of
metadata about the resource, which would always be returned as an XDI
document (meaning an XML document navigable using XRIs by an XDI processor).


Let me know if you'd like more information about the work of the XDI TC (or
feel free to join it as an observer - see
http://www.oasis-open.org/committees/xdi).

Best,

Thats a good question. Its not clear to me that there is one thing you'd do
with XRIs within the context of a browser. XRIs identify resources, they
don't imply specific application behavior. In fact, the same can be said of
http or mailto URIs, except that everyone (except those nutty semantic web
guys ;-) use HTTP and MAILTO uris in the same way, so there are standard
behaviors associated with them.

As for XRIs, I'd propose, as a first cut, that the browser could look for a
a X2R local access service associated with the XRI's identifier authority.
(X2R is the default local access service defined in the spec). The browser
could perform an HTTP get to that X2R local access endpoint (X2R is really
just the base HTTP semantics applied to an XRI resource). 

The return result would be a document displayable in a browser with further
XRI or HTML links to other documents or resources. RDDL is an an extension
to XHTML that does exactly this (http://www.rddl.org), allowing
machine-readable markup embedded in the XHTML so that the same document can
be consumed both by humans through a browswer and by machines using
RDDL-aware parsing. 

This is something that doesn't neccesarily need formalization. I'd propose
someone write a plugin for the major browsers and see how it works and how
popular it is... good ideas tend to evolve and are rarely the product of
instaneous genius. XRI being a good example ;-)
