Extensible Data Gateway Environment
JPL’s Extensible Data Gateway Environment (EDGE) is a data integration platform designed to facilitate high-performance geospatial data discovery and access with the ability to support multi-metadata standard specifications. EDGE, an Apache Foundation incubator project, is designed with two main building blocks: data aggregation service and enterprise geospatial indexed search cluster. The data aggregation service provides web service interfaces for searches, metadata packaging, and data access. Aggregation often involves retrieving data from two or more sources and packaging the resulting sets into a single response to the requestor. It could also serve as a proxy to other local/remote services to reduce the number of interfaces a requestor has to access. The enterprise geospatial indexed search cluster, which currently supports Apache Solr and ElasticSearch, is a horizontal scale cluster for faceted search with geospatial support.
