IANA has registered the following media types for use with LwM2M:
OMA is requesting IANA to register a new SenML Label for LwM2M object links in the "Sensor Measurement Lists (SenML) Parameters" registry, "SenML Labels" sub-registry:
The IANA Structured Syntax Suffix Registry requires a pointer to the latest revision of [LightweightM2M_TS]. That pointer needs to be stable, i.e. when OMA revises the document, there should be no need to update that link in the IANA registry. Due restrictions of the current standard publication process, publication of the [LightweightM2M_TS] in an additional location will be used to provide such a stable link for the IANA registry to refer to the latest TS for this Enabler, [LightweightM2M_TS]. The filename of the document referred by the IANA link is: OMA-TS-LightweightM2M-V1_1.zip. The document filename does not contain the date or document status.
In addition to the standard publication process, the documents [LightweightM2M_TS_Core] and [LightweightM2M_TS_Transport] has to be copied into the “Documents for External Reference” directory, and date and status have to be removed from the filename, such that it can be referenced externally as http://www.openmobilealliance.org/tech/extref/OMA-TS-LightweightM2M-Core-V1_1.zip or http://www.openmobilealliance.org/tech/extref/OMA-TS-LightweightM2M-Transport-V1_1.zip.
