The goal of the Terminology Core Common Model (TCCM) is to accomodate terminology resources from disparate data models. It will, by necessity, assemble its data from ouside (ideally definitive) sources.
The TCCM model is the set of LinkML-based definitions of the data models core to TCCM.
Not to be confused with TCCM Model (full spec).
TCCM Model (lite) is a much simpler version of the model, used by the current TCCM API.
TCCM Model (full spec) is in development, but is ultimately intended to supplant the existing, 'lite' version of the model.
