Abstract

The Government Information Locator System (GILS) is a component of the National Information Infrastructure (NII) which provides electronic access to sources of publicly accessible information maintained throughout the Federal Government. GILS is an internetworking information resource that identifies other information resources, describes the information available in the referenced resources, and provides assistance in how to obtain the information either directly or through intermediaries. The GILS core content which references each Federal information system holding publicly accessible data or information is described in terms of mandatory and optional core elements.
