Metadata collection is the systematic process of collecting metadata keys that manage all the relevant metadata information associated with the specific dataset or system. In custom metadata collection, metadata keys acts as identifiers for a specific attributes, characteristics or properties of the data by providing a structured overview of the dataset. This approach enables the user for efficient retrieval and management of the metadata, contributing to the enhanced data understanding and overall system functionality.

Metadata collections are classified into three categories.

Global collection: Global collection is a default collection created by the system when the initial key is defined in the metadata collection. By default, the global collection is always in published status. Users can directly use this collection to define Metadata keys.

Custom collection: Custom collections are user created collections to define metadata keys. Admin can create up to 50 custom collections in the system. By default, any custom collection created by users are in draft status and it is changed to published once the collection is published.

In the metadata collection screen, select a custom collection and click option to view the following options.

Metadata collection options

① Views the collection details.

② Adds a rule to the collection

③ Publishes the collection.

④ Deletes the collection.


  • When the collection is in draft status, "View details", "Add Rule", "Publish" and "Delete" options are enabled.
  • When the collection is in published status, only "View details" and "Add Rule" are enabled.

Reserved collection: Reserved collections are created, managed and are used by the system for the metadata like file type, file size, created date etc. This collection is always in published status.
