Catalogue service plays an important role in helping requestors to find the suitable geospatial data and services over the Web. The Open Geospatial Consortium has developed and recommended an ebRIM profile of Catalogue Services for the Web for implementing a catalogue service. Metadata for data and services registered in CSW is described by following the existing geographic metadata standards usually. The search functionality is limited to the direct match of keywords from metadata without

Web Ontology Language (OWL) provides a mechanism to enable the use of semantics. OWL-S uses OWL to describe the semantics for Web service. This paper explores the semantic representation of geospatial data and services to enable the semantic search in CSW based on the semantic relationship defined in OWL/OWL-S. Such semantics are organized in CSW through extending ebRIM elements. The paper also illustrates how such semanticallyaugmented CSW can facilitate service chaining and assist in dynamic discovery and/or derivation of geospatial information.
