    "abstract": "This document describes the \"tag\" Uniform Resource Identifier (URI) scheme. Tag URIs (also known as \"tags\") are designed to be unique across space and time while being tractable to humans. They are distinct from most other URIs in that they have no authoritative resolution mechanism. A tag may be used purely as an entity identifier. Furthermore, using tags has some advantages over the common practice of using \"http\" URIs as identifiers for non-HTTP-accessible resources. This memo provides information for the Internet community.",
