  5. EPA Search • The EPA controlled vocabulary and other metadata elements are captured to improve search results in the EPA search engine • Broad searches are filtered using the controlled vocabulary, metadata entries, and full-text of selected items before a full search is conducted • Search results are delivered in a tiered structure that improves access to the best resources on the EPA Web site

  7. Terminology Reference System • The EPA’s Terminology Reference System (TRS) was created as a single resource of environmental terminology for the Agency by compiling collections of terms from EPA and other sources. • The TRS is one of the EPA’s System of Registries (SoR), providing a gateway and search capability • These registries are a link in EPA's information architecture and are a component to the National Environmental Information Exchange Network (Network) • Specifically, the SoR was developed to support the Agency's data standards program and numerous Agency information technology initiatives
