PCC Extensions (4.0)

Apart from the built-in data models for PCC, you can also create your own data models using the Development Toolkit(3.1).

The data models are defined in XML format and then packed up in an *.mzp file that is committed into the system using Command Line Interface(3.1). They will then be available in the regular web interface for provisioning.

To create a PCC Extension data model:

In your DevKit directory, go to the /devkit-<version>/pcc_generation_tools/example/model/ folder.

Here you will find four example XML files that you can use as a starting point if you do not want to start creating your model from scratch.
Create your data model(s).
Create a *.jar file of your data model(s) by running the following command:
```
java -jar mzcli.jar <user name>/<password> --host <platform host> --port <platform port> generate_pcc_classes build/pcf.jar model -resource resource
```
Hint!

If you have configured a properties file for mzcli as described in mzcli(3.1) you can omit <user name>/<password> --host <platform host> --port <platform port> and you will be prompted for the password.
You should now have a *.jar file created in a new directory called build on the same level as the model folder stated in step 1.
Go to the devkit-<version> directory and create an *.mzp file of your *.jar file by running the following command:
```
java -jar lib/devkit.jar pcreate "<package name>" 1.0 pcc_generation_tools/example/build/<package_name_1.0>.mzp -level platform file=pcc_generation_tools/example/build/<package_name>.jar
```
You should now have an *.mzp file created in the same build folder as in the previous step.
Copy the *.mzp file to the platform pod by running the following command:
```
kubectl cp <package_name_1.0>.mzp platform-0:/opt/mz -n <namespace>
```
Log into the platform pod by running the following command:
```
kubectl exec -n <namespace> -it platform-0 -- bash
```
Commit the package into your system by running the following command:
```
mzsh <user name>/<password> pcommit <package_name_1.0>.mzp
```
Restart the ui pod by running the following command:
```
kubectl rollout restart deployment/ui
```
The new data model(s) should now be visible when you click on PCC Extensions in the Manage view in Desktop.

There is an example of a 5G PCF Rules model included in the Development Toolkit(3.1).
