Background
Each OMA DM Objects is specified in 3 different formats:
• Definition in TS (Normative)
• Graphical form (informative)
• XML file (informative)
• Most useful in implementations
LWM2M need at least objects to be defined in the TS and as XML File
With thousands of node definitions it is easy with misalignments

4. Public2015-01-224
Goal with the tool
Objects in LWM2M 1.0 spec should only be defined once
• All other formats should be automatically created to avoid misalignment
• All objects in LWM2M 1.0 TS created in the tool
• Done in the candidate release of Dec 2013
• Centralized tool hosted by OMA needed for reusable resources in OMNA

Overview
Compatibility:
The tool store all information of the object in the objects XML file
