How to use the data model schema to understand and develop CWMP/USP data models
See https://data-model-template.broadband-forum.org for the current TR-106 specification.
TR-106 specifies data model guidelines to be followed by all CWMP (TR-069) Endpoints and USP (TR-369) Agents. These guidelines include:
As part of this data modeling framework, TR-106 defines two XML Schemas:
The Data Modeling (DM) Schema, which is used for defining all CWMP and USP data models. This makes data model definitions rigorous, and helps to reduce the danger that different implementations will interpret data model definitions in different ways.
The Device Type (DT) Schema, that allows a device to describe its supported CWMP data models. This description is both specific and detailed, allowing a Controller to know exactly what is supported by the device, including any vendor-specific objects and parameters. USP uses a different mechanism (GetSupportedDM message) for the same purpose; this mechanism is specified in TR-369.
The TR-106 GitHub repository contains the above schemas, support files (e.g., common bibliographic references and data types), and the TR-106 specification source. The rendered GitHub Pages documentation can be found at https://data-model-template.broadband-forum.org.
The TR-106 schemas and support files are also available at the CWMP data models and USP data models sites. These sites present integrated views of the CWMP and USP versions of the standard data models, and provide a convenient way of viewing current and past versions of the schemas and support files in context.
