W3C: This document describes the properties we desire of the Web and the design choices that have been made to achieve them. It promotes the reuse of existing standards when suitable, and gives guidance on how to innovate in a manner consistent with Web architecture.
Randy: Must read!
Excerpt: If a URI scheme exists that meets the needs of an application, designers should use it rather than invent one.
Good practice: Reuse URI schemes
A specification SHOULD reuse an existing URI scheme (rather than create a new one) when it provides the desired properties of identifiers and their relation to resources.
Consider our travel scenario: should the agent providing information about the weather in Oaxaca register a new URI scheme "weather" for the identification of resources related to the weather? They might then publish URIs such as "weather://travel.example.com/oaxaca". When a software agent dereferences such a URI, if what really happens is that HTTP GET is invoked to retrieve a representation of the resource, then an "http" URI would have sufficed.
Randy: In other words, the feed URI scheme does not follow the Web Architecture.
