N2 - The Geospatial Catalogue Web Service is a vital service for sharing and interoperating volumes of distributed heterogeneous geospatial resources, such as data, services, applications, and their replicas over the web. Based on the Grid technology and the Open Geospatial Consortium (OGC)'s Catalogue Service - Web Information Model, this paper proposes a new information model for the Geospatial Catalogue Web Service, named GCWS, which securely provides Grid-based publishing, managing and querying of geospatial data and services, and transparent access to the replica data and related services under the Grid environment. This information model integrates the information model of the Grid Replica Location Service (RLS)/Monitoring & Discovery Service (MDS) with the information model of OGC Catalogue Service (CSW), and refers to the geospatial data metadata standard ISO 19115, FGDC and the NASA EOS Core System and service metadata standard ISO 19119 to extend itself for expressing geospatial resources. Using GCWS, any valid geospatial user who belongs to an authorized Virtual Organization (VO) can securely publish and manage geospatial resources, especially querying on-demand data in the virtual community and getting it back through data-related services that provide functions such as subsetting, reformatting, reprojection etc. This work facilitates the sharing of geospatial resources and interoperation under the Grid environment, and implements Grid enabled geospatial resources and geospatially enabled Grid technologies. It also enables researcher to focus on science, and not on issues with computing ability, data location, processing and management. GCWS also is a key component for workflow-based virtual geospatial data producing.
