BYRD doesn’t constrain you to a built-in static data model. Instead, you can build your own data model or choose an existing one from the Data Model Exchange. The Data Model Exchange is the market place built into BYRD. From there you can choose and buy data models and services, and you can also offer your own data models to other organizations.
Furthermore, you can modify the data model and adapt it to your needs. You can change layouts and you can create, modify, or delete attributes and categories and link them using drag & drop.
