A Trivial Convention for using HTTP in URN Resolution Status of this Memo ===================This memo defines an Experimental Protocol for the Internet community. This memo does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited. Abstract: =========The Uniform Resource Names Working Group (URN-WG) was formed to specify persistent, location-independent names for network accessible resources, as well as resolution mechanisms to retrieve the resources given such a name. At this time the URN-WG is considering one particular resolution mechanism, the NAPTR proposal [1]. That proposal specifies how a client may find a "resolver" for a URN. A resolver is a database that can provide information about the resource identified by a URN, such as the resource's location, a bibliographic description, or even the resource itself. The protocol used for the client to communicate with the resolver is not specified in the NAPTR proposal. Instead, the NAPTR resource record provides a field that indicates the "resolution protocol" and "resolution service requests" offered by the resolver.This document specifies the "THTTP" resolution protocol -a trivial convention for encoding resolution service requests and responses as HTTP 1.0 or 1.1 requests and responses. The primary goal of THTTP is to be simple to implement so that existing HTTP servers may easily add support for URN resolution. We expect that the databases used by early resolvers will be useful when more sophisticated resolution protocols are developed later.

Retrieving the resource identified by a Uniform Resource Identifier (URI) [1] is only one of the operations that can be performed on a URI. One might also ask for and get a list of other identifiers that are aliases for the original URI or a bibliographic description of the resource the URI denotes, for example. This applies to both Uniform Resource Names (URNs) and Uniform Resource Locators (URLs). Uniform Resource Characteristics (URCs) are discussed in this document but only as descriptions of resources rather than identifiers.A service in the network providing access to a resource may provide one or some of these options, but it need not provide all of them. This memo specifies an initial set of these operations that can be used to describe the interactions provided by a given access service. It also suggests guidelines that should be adhered to when those operations are encoded in a protocol.
