URN Specification for the oneM2M Namespace Identifier (NID) Namespace Identifier: onem2m Version: 1 Date: 2022-11-14 Registrant: Name: oneM2M Partnership Project Address: ETSI 650, route des Lucioles 06921 Sophia-Antipolis Cedex France Designated contact Role: oneM2M Secretariat Email: onem2m_contact&list.onem2m.org Purpose: The Namespace Identifier (NID) 'onem2m' for Uniform Resource Names (URNs) will be used to identify resources published by the oneM2M Partnership Project. These might include published standards or protocols that it defines and which make use of URNs. These namespaces are globally unique. The URN namespace will be used in public networks by clients to configure and manage resources in the network. It is the servers that will enforce the uniqueness of the namespaces by using the namespace and the XPath associated with the managed node in the network, when accessing a resource. Syntax: The syntax of namespace specific strings for the 'onem2m' namespace is in Uniform Resource Names (URNs) [RFC8141]. The entire URN is case-insensitive. Assignment: oneM2M will maintain the list of registered subtrees that use the 'onem2m' NID at https://wiki.onem2m.org/index.php?title=OneM2M_URN_Namespace, in the oneM2M URN Namespace registry. It will describe the , how the namespaces will be allocated, and how experimental namespaces can be used within the allocated URN. oneM2M will manage resource classes using the 'onem2m' NID and will be the authority for managing resources and associated subsequent strings. oneM2M will guarantee the uniqueness of the strings themselves, by validating it against the existing content of the registry. It may also permit secondary responsibility for certain defined resources. Once a subtree assignment is made, it cannot be deleted or reassigned. oneM2M may allow for use of experimental type values in specific subtrees, for testing purposes only. Note that using experimental types may create collision as multiple users may use the same values for different resources and specific strings. All experimentation must follow the guidance set forth in A Uniform Resource Name (URN) Namespace for Examples [RFC6963]. Interoperability: There are no known interoperability issues at this time. Security and Privacy: There are no additional security considerations that are normally associated with the use and resolution of URNs in general, which are described in Function Requirements for URN [RFC1737], Uniform Resource Names (URNs) [RFC8141]. Resolution: It is not foreseen that URNs within this namespace will undergo resolution. Documentation: Documentation can be found at https://wiki.onem2m.org/index.php?title=OneM2M_URN_Namespace.
