Oops... As Simon suggests, I forgot to ask which variant of EA you were using...

For the record, in your exampe, Data Model is a View Schema1 is a Package in EA parlents... Model is a Model or a Project Root (depending on which part of the UI you are talking to)... All the project roots (and there can be more than one) sit inside a Project or Repository (again depending on which part of the UI you talk to).
Thus you get the situation that a Project contains multiple Project Roots...
In the documentation, Project Roots are packages, Views are packages and Packages are packages. As George Orwell would say - All packages are equal, but some are more equal than others...
If you're confused you may like to try my nominations:
EA allows for a number of containers:
The Repository - a single instaceof either a .EAP file or a database schema.
The Repository contains one or more Subjects.
Each Subject may contain a number of Views
Each View may contain a number of Packages
Each Package may, itself contain, Packages
Slightly less confusing I'd submit...
