Introduction Authorization policies are an important component of presence [RFC2778]. They allow the presentity to grant access to specific pieces of information to watchers. Authorization policies have been designed to be extensible. For this reason [I-D.ietf-simple-common- policy-caps] defines a generic Extensible Markup Language (XML) based format for representing policy capabilities. That format applies to many policy types, including location and presence. This specification extends that one by defining policy capabilities specific to geographic location information. Those policy capabilities correspond to the conditions, actions and transformations defined in [I-D.ietf-geopriv-policy]. Guenther & Tschofenig Expires December 23, 2006 [Page 3] Internet-Draft Geopriv Policy Capabilities June 2006 2. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Guenther & Tschofenig Expires December 23, 2006 [Page 4] Internet-Draft Geopriv Policy Capabilities June 2006 3. Structure of Geopriv Policy Capabilities The structure of common policy capability documents is defined in [I-D.ietf-simple-common-policy-caps]. In that specification, each policy capability document has three components - a list of supported conditions, a list of supported actions, and a list of supported transformations. This specification merely extends that document with the conditions, actions and transformations defined in [I-D.ietf-geopriv-policy]. It does so by defining the following empty elements: civic-loc-condition geospatial-loc-condition distribution-transformation retention-tranformation keep-rules-transformation civic-loc-transformation geospatial-loc-transformation Each of these elements indicates whether the respective attribute in [I-D.ietf-geopriv-policy] is supported. All of these elements are defined within the namespace: urn:ietf:params:xml:ns:geopriv-policy-capabilities Guenther & Tschofenig Expires December 23, 2006 [Page 5] Internet-Draft Geopriv Policy Capabilities June 2006 4. XML Schema Guenther & Tschofenig Expires December 23, 2006 [Page 6] Internet-Draft Geopriv Policy Capabilities June 2006 5. Example Document The following document indicates that the identity and validity conditions are supported, each of which is defined in [I-D.ietf- geopriv-common-policy], while no support of sphere conditions is indicated. Furthermore, the example indicates that the geolocation- specific condition named civic-loc-condition is supported. With respect to transformations, the example gives the indication that the geolocation-specific transformations named keep-rules-transformation is supported. This is also the case for geospatial-loc- transformations, namely, for latitude and longitude values, but not for altitude values: Guenther & Tschofenig Expires December 23, 2006 [Page 7] Internet-Draft Geopriv Policy Capabilities June 2006 6. Security Considerations This specification does not introduce any new security considerations beyond those discussed in [I-D.ietf-simple-common-policy-caps].
