Introduction + + CableLabs is a non-profit research and development consortium that is + dedicated to pursuing new cable telecommunications technologies and + to helping its cable operator members integrate those technical + advancements into their business objectives. Within CableLabs, + specification activities are organized into projects such as + DOCSIS(R), PacketCable(TM), and OpenCable(TM), and technical work is + conducted within focus teams. Product vendors, manufacturers, and + cable operator members are invited to join the focus teams that + create technical specifications. + + Occasionally, CableLabs specification efforts require identifiers in + a managed namespace so that they are unique and persistent. To + ensure that the uniqueness is absolute, the registration of a + specific Uniform Resource Name (URN) [RFC2141] Namespace Identifier + + + + + +Cardona, et al. Informational [Page 2] + +RFC 6289 URN Namespace for CableLabs June 2011 + + + (NID) for use by CableLabs is being specified in this document, in + full conformance with the NID registration process specified in + [RFC3406]. + +2. URN Specification for CableLabs + + Namespace ID: + cablelabs + + Registration information: + registration version number: 1 + registration date: 2011-04-18 + + Declared registrant of the namespace: + Registering organization + Name: Cable Television Laboratories, Inc. + Address: 858 Coal Creek Circle, Louisville, CO 80027, USA + Designated contact + Role: Manager, Standards + Email: ietf_standards@cablelabs.com + + Declaration of syntactic structure: + The Namespace Specific String (NSS) of all URNs that use the + "cablelabs" NID will have the following structure: + + {CLclass}:{CLClassSpecificString} + + The "CLclass" is a US-ASCII string that conforms to the URN + syntax requirements specified in [RFC2141] and defines a + specific class of resource type. Each class will have a + specific labeling scheme that is covered by + "CLClassSpecificString", which also conforms to the naming + requirements of [RFC2141]. + + CableLabs maintains the CableLabs' Assigned Names and Numbers + [CANN] specification that will contain the assignment of + CableLabs' resource classes and the specific registration values + assigned for each resource class. + + Relevant ancillary documentation: + CableLabs publishes information regarding the registered + resources in the CableLabs' Assigned Names and Numbers + specification ([CANN]). + + + + + + + + +Cardona, et al. Informational [Page 3] + +RFC 6289 URN Namespace for CableLabs June 2011 + + + Identifier uniqueness considerations: + CableLabs will manage resource classes using the "cablelabs" NID + and will be the authority for managing resources and associated + subsequent strings. CableLabs is expected to guarantee the + uniqueness of the strings themselves, or it may permit secondary + responsibility for certain defined resources. + + CableLabs could allow the use of experimental type values for + testing purposes only. Note that using experimental types may + create collisions as multiple users may use the same values for + resources and specific strings. + + Identifier persistence considerations: + CableLabs will update the CableLabs' Assigned Names and Numbers + specification ([CANN]) to document the registered resources that + use the "cablelabs" NID. + + Process of identifier assignment: + CableLabs will provide procedures for registration of each type + of resource that it maintains. Each such resource may have + three types of registration activities: + + 1. Registered values associated with CableLabs documents or + services + 2. Registration of values or sub-trees to other entities + 3. Name models for use in experimental purposes + + Process for identifier resolution: + The namespace is not listed with a resolution discovery system; + this is not applicable for this URN registration. + + Rules for lexical equivalence: + No special considerations; the rules for lexical equivalence of + [RFC2141] apply. + + Conformance with URN syntax: + No special considerations. + + Validation mechanism: + None specified. URN assignment will be handled by procedures + implemented in support of CableLabs activities. + + Scope: + Global + + + + + + + +Cardona, et al. Informational [Page 4] + +RFC 6289 URN Namespace for CableLabs June 2011 + + +3. Example + + The following example represents a hypothetical URN that could be + assigned by CableLabs. + + urn:cablelabs:packetcable-example:ue:rst-sample + + This example defines the URN to be used for User Equipment (UE) + conforming to the sample Residential SIP Telephony (RST) application + specified within CableLabs' PacketCable RST specification suite. + +4. Namespace Considerations + + CableLabs develops specifications that may require the use of data + models. URN Namespaces are key constructs to manage the definitions + of those data models reliably with persistence and uniqueness. + + The use of URNs should also help specification authors to maintain + different versions of URNs and dependencies between URNs across + different versions of CableLabs specifications if they so wish. + +5. Community Considerations + + Participants involved in the development and usage of CableLabs + specifications and cable industry deployments will benefit from the + publication of this namespace by providing consistent and reliable + names for the XML namespaces, schema locations, and similar + identifiers of physical data models published within CableLabs + specifications. + + The CableLabs specifications are publicly available and are licensed + to manufacturers on a nondiscriminatory basis. CableLabs will + maintain the allocation of resources for the "cablelabs" NID within + the following specification: "CableLabs' Assigned Names and Numbers" + [CANN], which will be publicly available for viewing. CableLabs will + also maintain the corresponding specifications where the registered + resources are referenced or used. + +6. IANA Considerations + + This document adds a new entry ("cablelabs") in the urn-namespaces + registry. This is the defining document. The entry can be found in + the "Uniform Resource Names (URN) Namespaces" registry available from + the IANA site (http://www.iana.org) and any associated mirrors. + + + + + + + +Cardona, et al. Informational [Page 5] + +RFC 6289 URN Namespace for CableLabs June 2011 + + +7. Security Considerations + + There are no additional security considerations other than those + normally associated with the use and resolution of URNs in general, + which are described in [RFC1737], [RFC2141], and [RFC3406]. + +8. Acknowledgements + + The authors wish to thank Alfred Hoenes, Ted Hardie, and Peter Saint- + Andre for their useful comments and suggestions.
