The Government Information Locator Service (GILS) is a response to the need of users to be able to identify, locate, and access or acquire publicly available federal information resources. GILS uses ANSI/NISO Z39.50, the American National Standard for information retrieval, and other relevant standards to support the deployment of agency-based, network accessible locators. The third in a series of projects conducted by study teams at Syracuse University on federal locator systems, the current project produced: (1) an application profile for the use of Z39.50 in GILS; (2) a background document describing design decisions and assumptions of the project team and used to inform stakeholders and build consensus; (3) three reports describing technical and policy issues of concern to the GILS initiative; and (4) this final report, which details the project's activities, identifies remaining issues for future GILS activities, and recommends a series of next steps. The completion of this project has laid the technical groundwork for GILS implementations and identified two important next steps to move the GILS initiative forward: establishing an interoperability testbed for demonstrating interoperable GILS products; and continuing to stimulate the market for GILS products and services and encouraging federal agencies to implement GILS locators. The project also developed a list of recommendations that address both short-term requirements of GILS and its long-term viability. It is noted that, although the technical groundwork has been laid and a government-wide policy framework is being developed, future emphasis on GILS development will need to shift to individual agencies. Additional information related to the project is provided in 17 attachments. (BBM)
