This page presents some of the metadata products and services supported by the EDR and describes how to use some of the features of the EDR to conduct metadata management activities. If you are a first time user of the EDR, you will want to read the
Introduction to learn more about the EDR registries and their content. You may also wish to review the following metadata activities.

Please note that the EDR does not contain the environmental data itself, but rather information that describes the data to make it more meaningful. If you are interested in environmental data, and not environmental metadata, you may want to select
Help to view related data sources.

Introduction |
The Environmental Data Registry (EDR) is a comprehensive, authoritative source of reference information about the definition, source, and uses of environmental data. The EDR catalogs the Environmental Protection Agency's (EPA) major data collections and helps locate environmental information of interest. As the major tool supporting the Agency's data standards program, the EDR records and disseminates information about Agency data standards and the standard-setting process. To learn more about what the EDR offers see the
Introduction.

Data Standards
Newsletter
Subscription
|
The vision for EPA's data standards program is to promote the efficient sharing of environmental information among EPA, states, tribes, and other parties through the cooperative development of data standards. The
Data Standards
page allows users to access any of the Agency data standards and to view information on the status, implementation dates, business rules, and data elements.
Subscribe to the EDR to receive news and notifications of EDR updates. The
Registry Update, EPA's newsletter about data standards, covers a variety of data standards-related topics.

Registration
|
Using the EDR
searches, you can search for metadata by information resource (Data Systems, EPA Data Standards, etc.), by text or text string, alphabetically, numerically, or by a specific metadata item (Data Elements).
Visit the EDR Registration page to register data elements from an EPA information system and make the data element metadata available to the public and other system developers.

How to . . . |
|
Implement Standards |
The
Implement Standards
page might allow program managers, systems managers, and systems developers who are responsible for implementing data standards in their application systems to ensure consistently defined and formatted data elements and sets of data values to efficiently share environmental information.
|
|
Harmonize Data |
A data harmonization analyst compares two or more systems, usually within a program area, with the goal of reducing data redundancy and inconsistencies and improving the quality and format of data. An analyst may be interested in data mapping, data normalization, or data integration. The EDR supports the harmonization process by providing a data mapping capability. The
Harmonize Data
page describes the process of searching for related data elements in multiple information systems, and selecting data elements to compare. Users can also compare their metadata to EPA data standards. An analyst can use the comparison to guide system integration or data changes resulting in consistent data meaning.

|
Develop Systems |
The
Develop Systems
page can assist computer programmers or systems analysts interested in the representation, format, definition, and valid values of a standard to develop or reengineer application systems.
