Catalog Unique Identifier

The Dateno system assigns each catalog a unique identifier when the catalog is registered in the dataset registry. A catalog unique identifier is a persistent string that uniquely identifies the catalog across all API methods and metadata structures. These identifiers typically follow the format cdi00000xxx.

Catalog unique identifiers remain stable even if the catalog contents change or the catalog is temporarily removed from the registry.

In the Dateno web application, the catalog identifier is displayed in the Source UID field on a dataset card.

In the Dateno API, catalog identifiers appear in the source.uid field of both dataset cards and dataset descriptors. Your application can use this identifier to relate datasets to their source catalogs.

To retrieve a complete description of a catalog, use the catalog identifier with the
Fetch Single Catalog request.
