3. Values#
Values are predefined options that can be assigned to certain properties.
Role#
Value |
Description |
|---|---|
Administrator |

Reader |
Read-only access. Can view the object but cannot modify or delete it. |
Primitive data types#
Although the ModelFed vocabulary allows you to define new data types, the primitive data types you can use are predefined and cover the most common data representations.
Common primitive data types include:
|
|
|
|
|
|
|
You can also extend this set by defining custom data types if needed, but these primitives form the foundation for most property values needs.
