Background
Metadata are key-value pairs. So all metadata keys (e.g. Difficulty) have a certain value (e.g. Easy, Medium or Hard for the key Difficulty).
The administrator defines the keys, and the author adds these keys to their items and selects a certain value.
Metadata keys that belong together are grouped into metadata libraries, which are also managed by the admin.
Functionalities
Metadata can help you, as an author, in various ways:
- You can show metadata in the item overview in the item bank.
- You can search for items with metadata in the item bank.
- You can filter on items with metadata in a scenario.
Metadata libraries
The metadata is managed by the administrator in metadata libraries.
A metadata library contains metadata keys that belong together. For example, a metadata library for Maths or for Geography.
The administrator:
- creates the metadata libraries
- adds metadata keys to the libraries
- determines in which folders in the item bank these metadata keys are available.
Metadata keys
There are different types of metadata keys:
- Numerical: the author can enter a numerical value
- Dropdown: the author can select one value for the metadata key
- Editable dropdown: the author can select one value for the metadata key and he can add new values.
- Multi-select dropdown: the author can select multiple values for the metadata key
- Editable multi-select dropdown: the author can select multiple values for the metadata key and he can add new values.
