EDG CS-W Interface
The EDG CS-W (Catalog Service for the Web) Interface supports arbitrary metadata schemas without complicating the search component of the EDG. When a metadata document is published to the EDG, the original metadata remains unchanged and is used when editing the metadata or when displaying the full metadata as part of search results. At the same time, the EDG is able to extract searchable elements into a uniform structure, standardize domain values across metadata standards, determine the topic category codes or content types of the metadata document, select key content for connecting to online resources, and assign a unique identifier to the record.
