8. Cataloging Data, Metadata and Resources
Once the data and metadata have been reviewed, validated, and approved, they are ready to be published in an online data catalog. Publishing data in a catalog makes them easier to discover, access, understand, and reuse by both internal and external audiences.
Why Catalog Data?
An online catalog provides several important benefits not limited to the following:
- Facilitates data discovery by making datasets searchable and easier to locate.
- Improves data understanding by allowing users to review metadata, documentation, and related resources before requesting access.
- Supports informed data use by providing information on methodology, coverage, quality, and terms of use.
- Enables secure data access by applying appropriate access controls and restrictions where necessary.
- Promotes data reuse and transparency by increasing the visibility and accessibility of research and statistical outputs.
How It Works
Open-source cataloging platforms such as NADA (National Data Archive) can readily ingest metadata documented using the DDI Codebook (DDI-C) and Dublin Core (DCMI) standards. Once imported, the metadata can be published through a searchable web interface, alongside data files, documentation, questionnaires, reports, and other related resources.
Detailed guidance on adding metadata and data content to a NADA catalog is available in the NADA Documentation:-
