METADATA DESCRIPTORS

Metadata Descriptors Management

Descriptors are the fields that could be associated with records. These descriptors are grouped into metadata schemas (as a way of organizing and managing them).

Each record is associated with a metadata schema when it is created, defining the set of fields that are available to it. Descriptors are an important part of the preservation, since data from the records can be stored in a simple way, then filter and display them in the interface.

Basic aspects to take into account:

1. What type of records will be associated with this descriptor.

2. To which metadata schema this descriptor will belong.

3. What type of data will be stored in it.

4. If it belongs to a parent descriptor.
