# The CDM's Rosetta model

The CDM declares its data model in Rosetta. Each file holds one namespace and one kind of declaration, such as `base-datetime-type.rosetta` and `base-datetime-enum.rosetta`.[^rosetta_to_linkml.py] The converter reads the type, choice, enumeration and type alias declarations. It leaves the functions and rules out, because they compute or classify data and are not data.[^about.md]
