Abstract

   This document defines the "info" Uniform Resource Identifier (URI)
   scheme for information assets with identifiers in public namespaces.
   Namespaces participating in the "info" URI scheme are regulated by an
   "info" Registry mechanism.

1.  Introduction

   This document defines the "info" Uniform Resource Identifier (URI)
   scheme for information assets that have identifiers in public
   namespaces but are not part of the URI allocation.  By "information
   asset" this document intends any information construct that has
   identity within a public namespace.

1.1.  Terminology

   In this document, the keywords "MUST", "MUST NOT", "SHALL", "SHALL
   NOT", "SHOULD", "SHOULD NOT", "MAY", "MAY NOT", and "RECOMMENDED" are
   to be interpreted as described in RFC 2119 [RFC2119] and indicate
   requirement levels for compliant implementations.

1.2.  Information Assets

   There exist many information assets with identifiers in public
   namespaces that are not referenceable by URI schemes.  Examples of
   such namespaces include Dewey Decimal Classifications [DEWEY],
   Library of Congress Control Numbers [LCCN], NISO Serial Item and
   Contribution Identifiers [SICI], NASA Astrophysics Data System
   Bibcodes [BIBCODE], and National Library of Medicine PubMed
