+A TEA Product object has the following parts:
+
+- __uuid__: A unique identifier for the TEA product
+- __name__: Product name
+- __identifiers__: List of identifiers for the product
+   - __idType__: Type of identifier, e.g. `tei`, `purl`, `cpe`
+   - __idValue__: Identifier value
+- __components__: List of TEA components for the product
+   - __uuid__: Unique identifier of the TEA component
 
 The TEA Component UUID is used in the Component API to find out which versions
 of the Component that exists.
