EPA and CBP Metadata: An Enterprise Approach to Data Sharing
Track: Spatial Data Infrastructure
Authors: John Wolf, David Parrish, Dan Spinosa

An enterprise approach to data sharing requires careful consideration of technology choices, standards adherence, policy implementation, and user requirements. The EPA's Environmental Dataset Gateway (EDG) is an enterprise metadata catalog that connects EPA's data resources, pointing users to thousands of datasets, services, and applications. The Chesapeake Bay Program (CBP), a unique regional partnership that includes EPA, other federal agencies, states, and citizen advisory groups, has developed its own metadata catalog to complement the EDG. Both the EDG and the CBP Catalog are built on Esri's open-source Geoportal Server software. A federated search capability enables users to search for and discover geospatial resources in both catalogs using in a single search. This presentation will provide an overview of the capabilities of and relationships between these catalogs as well as external resources (e.g. Data.gov, Geo.Data.gov, and the GeoPlatform) as a case study for others interested in data sharing practices.
