RE: [xri] Update to Metadata Issue #1: Add $t Tag for Identifier Metadata

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

Mike, two quick notes RE this thread:

1) The concept of resolution of $ space XRIs is pretty new and applies
(IMHO) only to "dictionary" services -- something we talk about extensively
in the context of XDI (which I fully recognize is a different TC). But the
XRI specs says nothing about resolution of the $ space and I don't think
they need to. What's been being discussed is simply how it might work if it
was applied (given that Marty has a use case for doing so).

2) Marty's "dreaming" about a $t type definition language and local
resolution service is forward thinking about how it might work and not at
all in the scope of XRI 2.0. The only thing being discussed in the scope of
2.0 is the addition of a $t tag to Metadata (item #3, after the two Syntax
items, on tonight's/tomorrow's calls.)

I'd suggest we talk over the use cases and requirements on the call. If more
documentation is needed, we can agree on that and assign the action item.

I keep trying to fit this idea of using a different approach to
resolution of an XRI into the XRI architecture and continue to have a
hard time understanding why local access isn't the appropriate solution.
