The functionality should provide CRUD operation to manage mapping between file extensions and Data types.
The file extension entity should contain:
- File extension (.mrc, .marc) - the primary key
- Set of Data types (MARC, EDIFACT, Delimited etc.). The Data type itself could be an ENUM
- Block import - boolean value, should not be null
- Standard metadata component
There should be a separate table to store a default set of tenant extensions
