**Model Metadata Definition**

As already told at the beginning, **models** is the unique folder managed both by the Community and the Enterprise Edition. It contains all data-mining models usable by the Knowage Function Catalog.

For each model is possible to define its metadata, download and/or delete the model using directly the tree options:
