NASIS-Related Metadata

Metadata are the definitions of the database structures for NASIS and its related databases. This includes the structure of each table, data element definitions, lists of codes, and relationship information.

From these pages you can browse and print the documents and reports that have traditionally been part of the NASIS Database Structure Guide. In addition, a variety of new metadata documents, diagrams, and downloads are also available.

If you are already familiar with the contents of the NASIS metadata documents, reports, and diagrams, you may simply navigate directly to the metadata category for which you wish to obtain metadata.
