Abstract

This document describes the "tag" Uniform Resource Identifier (URI)scheme. Tag URIs (also known as "tags") are designed to be uniqueacross space and time while being tractable to humans. They aredistinct from most other URIs in that they have no authoritativeresolution mechanism. A tag may be used purely as an entityidentifier. Furthermore, using tags has some advantages over thecommon practice of using "http" URIs as identifiers fornon-HTTP-accessible resources. This memo provides information for the Internet community.
