# system.kanoa.inventory.addModel(modelInfo, userId)

Adds a new model to the inventory catalog, or updates an existing one when `modelId` is included in `modelInfo`. 
A model represents a specific equipment/asset model made by a manufacturer (e.g. a catalog entry for a pump or motor model), 
distinct from a Part, which is an individual replaceable component. 
This upsert behavior is the only mechanism for modifying an existing model as there is no separate `updateModel` or `updateModelField` function.
