# BroadBand Forum Data Models (BBFDM)

`bbfdm` is an implementation developed by iopsys that conforms to Broadband Forum Data Models and which includes a list objects, parameters, events and operates used for CPE management through remote control protocols such as [TR-069/CWMP](https://cwmp-data-models.broadband-forum.org/) or [TR-369/USP](https://usp.technology/).


This implementation comprises of the three main components:

| Component  |                    Description                    |
| ---------- | ------------------------------------------------- |
| libbbfdm-api | It is a library that provides many APIs used to interact with UCI configurations, Ubus objects, JSON schema, CLI commands and memory management. It also provides a mechanism to add new objects, parameters, events and operates or extend the existing DM tree using json plugin or shared library plugin. |
| libbbfdm  | It's a libarry that provides the different data models supported by iopsys |
| bbfdmd | It's a deamon which used to expose data model objects over ubus |


## Design of bbfdm

`bbfdm` package is structred as follow:


```bash
├── bbfdmd
├── docs
├── libbbfdm-api
├── libbbfdm
│   ├── dmtree
│   │   ├── json
│   │   ├── tr104
│   │   ├── tr143
│   │   ├── tr181
│   │   ├── tr471
│   │   ├── vendor
│   ├── scripts
└── tools
```

- `bbfdmd` folder which contains the source code of bbfdm deamon.
More explanation on how this daemon works and all supported methods are presented in this file [BBFDMD](./bbfdmd/README.md)

- `libbbfdm` folder which contains the different data models supported by iopsys

	- `dmtree` folder which includes all supported Data Models and vendor extension objects. It contains 6 folders:

		- `tr181` folder : TR-181 Data Model files

		- `tr104` folder : Voice Services Data Model files

		- `tr143` folder : Diagnostics Data Model files

		- `tr471` folder : IPLayerCapacityMetrics Diagnostics Data Model files

		- `vendor` folder : Vendor Data Model files

		- `json` folder : TR-181 and TR-104 JSON files

	- `scripts` folder which contains all the scripts used to run the different types of diagnostics.

- `libbbfdm-api` folder which contains the source code of all API functions (UCI, Ubus, JSON, CLI and memory management). These API are used for GET/SET/ADD/Delete/Operate calls which can be called in internal or external packages.
All APIs exposed by libbbfdm-api are presented in this header file [libbbfdm_api.h](./libbbfdm-api/include/libbbfdm_api.h).

- `tools` folder which contains some tools to generate Data Model in C, JSON, XML and Excel format.
All supported tools are presented in this file[BBFDM Tools](./docs/guide/tools.md)

- `docs` folder which contains all documentation files.
