OMA LightweightM2M (LwM2M) Object and Resource Registry

OMNA can provide you with a unique Object or/and Resource Identifier: (Object ID) or (ResourceID).

To register a new (Object ID) or (Resource ID). Your submission will be redirected to GitHub Issues in lwm2m-registry.

OMA has developed an editor for creating LwM2M Objects & Resources.

The LwM2M Editor can be accessed here: Editor.
The XML schemas used by the LwM2M Editor can be found here: LWM2M.xsd and LWM2M-v1_1.xsd
The OMA Guidelines for the Creation and Registration of LwM2M Objects & Resources can be found here: Guidelines
Introduction to LightweightM2M can be found here: Introduction
Best Practices for LwM2m can be found here: Best Practice
LwM2M Registry API: LwM2M Registry API

The official publication of OMA LwM2M Objects and Resources is this page. However, the registration process is done via GitHub at: lwm2m-registry. IPSO Working Group, will review your registration. You can interact with this group via lwm2m-registry Issues.

The Vorto Project is an Eclipse Foundation open source initiative that aims to help compile and manage abstract device descriptions (information models). The scope includes:

Vorto Repository - an open platform where information models are shared
Vorto Domain Specific Language and editor - used to describe information models
SDK - helps reduce development time
