The design and implementation of a grid-enabled catalogue service

Abstract

Catalogue service is crucial to the sharing and utilizing of geographic information. This paper provides a new architecture and its implementation of a geographic information catalogue service that can effectively manage distributed geographic data and services. The catalogue service is based on the Open Geospatial Consortium (OGC) Catalogue Service for Web Specification and the ebXML Registry Information Model (ebRIM). The ebRIM is extended with ISO 19115 (including draft part 2) and ISO 19119 international standards for better description of geographic information. The adoption of the ebRIM and international standards will greatly advance the interoperability of the catalogue service and the sharing of the abundant geographic information. The catalogue service is Gridenabled to facilitate Grid’s abilities of on-demand, ubiquitous access to distributed computing, data, and services resources. The Grid-enabled catalogue service is GSI-supported which enables it to interoperate with other Grid Services in a secure way. By being integrated with RLS, MDS and other Gridenabled OGC Services, this Grid-enabled catalogue service prototype provides secure discovery, retrieval, and management of geographic data and services.
