        The Entity Category SAML Entity Metadata Attribute Types
                     draft-young-entity-category-01

Abstract

   This document describes a SAML entity attribute which can be used to
   assign category membership semantics to an entity, and a second
   attribute for use in claiming interoperation or support for entities
   in such categories.

   This document is a product of the Research and Education Federations
   (REFEDS) Working Group process.

1.  Introduction

   This document describes a SAML attribute, referred to here as the
   "entity category attribute", values of which represent entity types
   or categories.  When used with the SAML V2.0 Metadata Extension for
   Entity Attributes [SAML2MetadataAttr] each such entity category
   attribute value represents a claim that the entity thus labelled
   meets the requirements of, and is asserted to be a member of, the
   indicated category.

   These category membership claims MAY be used by a relying party to
   provision policy for release of attributes from an identity provider,
   to influence user interface decisions such as those related to
   identity provider discovery, or for any other purpose.  In general,
   the intended uses of any claim of membership in a given category will
   depend on the details of the category's definition, and will often be
   included as part of that definition.

   Entity category attribute values are URIs, and this document does not
   specify a controlled vocabulary.  Category URIs may therefore be
   defined by any appropriate authority without any requirement for
