            A Uniform Resource Name (URN) Namespace for the
                    Open Geospatial Consortium (OGC)

   This document describes a Uniform Resource Name (URN) namespace that
   is engineered by the Open Geospatial Consortium (OGC) for naming
   persistent resources published by the OGC.  The formal Namespace
   IDentifier (NID) is "ogc".

1.  Introduction

   The Open Geospatial Consortium (OGC) is a voluntary consensus
   standards organization.  Founded in 1994, the OGC produces many kinds
   of technical documents, including: standards, working drafts,
   technical reports, discussion papers, and XML schemas.  The OGC
   wishes to provide persistent, location-independent Identifiers for
   these resources.  Further, a number of OGC standards and application
   schemas of OGC standards are now used and/or referenced by standards
   specifications from other standards organizations, including OASIS,
   the IETF, IEEE, ISO, and OMA.

   The OGC core mission is to develop spatial interface and encoding
   specifications that are openly available and royalty free.  Products
   and services that conform to OGC interface specifications enable
   users to freely exchange and process spatial information across
   networks, computing platforms, and products.  Interoperability in
   such an environment is facilitated by the use of a system of
   persistent identifiers that are global in scope.  The OGC is the only
   standards organization whose mission is specifically focused in
   interfaces and encodings for geospatial content and services.

   Motivated by these concerns, the OGC would like to assign formal URNs
   to published resources in order to provide persistent, location-
   independent identifiers for them.  The process for registering a
   namespace identifier is documented in RFC 3406 [2].

   The official IANA registry of URN namespaces is available online:

   Registration Information:

   Declaration of syntactic structure:

      The Namespace Specific String (NSS) of all URNs that use the "ogc"
      NID will have the following structure:


      where the "OGCresource" is a US-ASCII string that conforms to the
      URN syntax requirements [1] and defines a specific class of
      resource type.  Each resource type has a specific labeling scheme
      that is covered by "ResourceSpecificString", which also conforms
      to the naming requirements of [1].  The only exception is that the
      character ":" shall not be used as part of the "OGCresource"
      string.  This is to avoid possible confusion.  Further,
      "OGCresource" is case sensitive.

      The OGC maintains a naming authority, the OGC Naming Authority
      (ONA), that will manage the assignment of  "OGCresources" and the
      specific registration values assigned for each resource class.

   Relevant ancillary documentation:

      The OGC Naming Authority (ONA) provides information on the
      registered resources and the registrations for each.  More
      information about ONA, the registration activities, and procedures
      to be followed are available at:

      An operational OGC URN "resolver" is available at
      http://urn.opengis.net/.  The resolver provides a registry of the
      currently member approved OGC URN's used in currently approved and
      implemented OGC standards.

      The OGC Naming Authority is a permanent OGC resource.  The
      documents and related OGC URN resources, such as the URN resolver,
      have stable URLs.  The ONA reference is

      There are a number of OGC Best Practice and Standards documents
      that define member agreements on the definitions for "OGCresource"
      and ResourceSpecificString.
