Although it makes perfect sense to have a generic URI (UR(L|N)) syntax, it does not follow that a generic URC syntax is useful, and what exactly would a generic URN resolution procedure be? A generic mechanism for identifying URCs as URCs would be good, but should be done immediately. Identifying suitable sets of characteristics for any URC, such that they support URN resolution, would also be good. Is that what you mean by a generic syntax? >We then develop proposed standards that define specific >URN syntaxes (hdl, path, ...), specific URC formats (like the >x-srs stuff for rating Internet resources that I will demo), and >specific URN resolution procedures (probably closely aligned with >specific URN syntaxes). I don't think that the WG should develop any of these. I think it should continue to act as a forum for critiquing the system builders' specifications, perhaps analogous to a media type advisory group [Larry, did the IETF ever do anything about that?]. I do think it would be reasonable for the WG to have an action item for evaluating these things (once they are available) and recommending how the IETF itself should use them. So, here's how I would butcher Leslie and Ron's rewrite of the charter, such that it would match what I think should be the goals of a URI working group. Note that I prefer a more aggressive schedule. ......Roy ===================== Description of the Working Group: The URI-WG is chartered to define a set of standards for the encoding of system-independent resource identification information for the use of Internet information services. The working group is expected to produce a set of documents that identify the requirements for system-independent resource identification, define the architectural components necessary to perform that identification, and specify the standard interfaces necessary to enable those components. As part of that work, the URI-WG has already identified the components of Uniform Resource Locators (URLs) and Relative URLs for resource location, Uniform Resource Names (URNs) for location-independent identity, and Uniform Resource Characteristics (URCs) for resource description and location redirection. Informational RFCs have been published regarding the desired properties of URLs (RFC 1736) and URNs (RFC 1737), and these may be updated by the working group after further implementation experience. Standards-track RFCs have been published on the syntax and semantics of URLs (RFC 1738) and Relative URLs (RFC 1808), and the URI-WG will continue to act as the forum for discussion regarding these specifications as they progress through the standards process. Work in progress includes specification of the desired properties of URCs, the syntax and semantics of URNs, and the specification of new URL or URN schemes. The working group will produce additional documents regarding the overall Uniform Resource Identification architecture (describing the roles of each component within the scope of Internet information services), and will develop recommendations for how the IETF should proceed in approving and/or registering new instances of URI components. These documents will provide a framework that allows Internet users, applications, and services to identify and access Internet resources, with appropriate consideration for issues of security and privacy. Goals and Milestones ==================== Aug 95 Desired properties of URCs published as informational RFC. Sep 95 URN syntax and semantics published as proposed standard RFC. Sep 95 Generic mechanism for identifying URCs as URCs published as informational or proposed standard RFC. Oct 95 Revise RFC 1738 (URLs), move to draft standard status. Oct 95 Mailserver and finger URL drafts to proposed standard. Dec 95 Revise RFC 1808 (Relative URLs) or move to draft standard status. Jan 96 Desired properties of URN resolution published as Informational RFC. Jan 96 URI Architecture published as Informational RFC. Jan 96 Update RFCs 1736 and 1737, if needed.
