Well, it all went very quiet for a while but glad to see that the URI Template Internet-Draft has just been republished:

"A New Internet-Draft is available from the on-line Internet-Drafts
directories.

Title : URI Template
Author(s) : J. Gregorio, et al.
Filename : draft-gregorio-uritemplate-01.txt
Pages : 9
Date : 2007-7-23

URI Templates are strings that can be transformed into URIs after
embedded variables are substituted. This document defines the
syntax and processing of URI Templates.

A URL for this Internet-Draft is:

URI templates should be a very useful publishing tool. Templates are already used by technologies such as OpenSearch - see here.
