AIST CS-W: an OGC-based distributed geospatial search engine for heterogeneous metadata

Abstract

This paper describes geospatial search engine software that supports the OGC catalog service CS-W as well as OpenSearch GEO, Time, and SRU extensions. The system is an enhanced version of existing AIST CS-W software [1], a key feature of which is to support http-based distributed search processing that can also support parallel geospatial searches. The system also provides the extensibility for various heterogeneous metadata profiles.
