Williams Expires December 30, 2004 [Page 3] Internet-Draft GSS-API Namespace Considerations July 2004 2. Introduction There is a need for generic and mechanism-specific extensions to the Generic Security Services Application Programming Interface (GSS-API). As such extensions are designed and standardized, both at the IETF and elsewhere, there is a non-trivial risk of namespace pollution and conflicts. To avoid this we set out guidelines for extending the GSS-API and create IANA registries of GSS-API namespaces. Williams Expires December 30, 2004 [Page 4] Internet-Draft GSS-API Namespace Considerations July 2004 3. Extensions to the GSS-API Extensions to the GSS-API can be categorized as follows: o Generic o Implementation-specific o Mechanism-specific o Language binding-specific o Any combination of two or all three of the last three Extensions to the GSS-API may be purely semantic, without effect on the GSS-API's namespaces. Or they may introduce new functions, constants, types, etc...; these clearly affect the GSS-API namespaces. Extensions that affect the GSS-API namespaces should be registered with the IANA< along with their specific effects on the GSS-API namespaces. Williams Expires December 30, 2004 [Page 5] Internet-Draft GSS-API Namespace Considerations July 2004 4. Generic GSS-API Namespaces All the function, constant and type names, as well as all the constant values specified in the base GSS-API specification for the basic generic GSS-API namespace. The generic GSS-API namespaces are: o Type names o Function names o Constant names for each type o Constant values for each type Williams Expires December 30, 2004 [Page 6] Internet-Draft GSS-API Namespace Considerations July 2004 5. Language Binding-Specific GSS-API Namespaces Williams Expires December 30, 2004 [Page 7] Internet-Draft GSS-API Namespace Considerations July 2004 6. Extension-Specific GSS-API Namespaces Extensions to the GSS-API may create additional namespaces. IANA registries SHOULD be created for any such new namespaces. Williams Expires December 30, 2004 [Page 8] Internet-Draft GSS-API Namespace Considerations July 2004 7. IANA Considerations The following registries should be established upon publication of this document as an RFC: o GSS-API Type Name Registry o GSS-API Function Name Registry o GSS-API Constant Name Registry o GSS-API Constant Value Registry o GSS-API Class/Header/Library/Module Name Registry Entries in these registries should consist of: o Namespace name o Symbol name or prefix, OR value or value range. o [optional] Reference to normative reference for the registration. o [optional] Programming language o [optional] Entry sub-type (e.g., "header name") o [optional] Mechanism OID(s) and/or OID prefix(es) associated with the entry o [optional] Magic o [optional] Expert Review (body or people who reviewed the registration) o [optional] Description (in English) Williams Expires December 30, 2004 [Page 9] Internet-Draft GSS-API Namespace Considerations July 2004 8.
