Protocols SPARQL Protocol

Extends RDF4J (Sesame) and is deployed as a Java servlet WAR on Tomcat exposing an HTTP SPARQL/stSPARQL endpoint.

  • Strabon is a spatiotemporal RDF store. You can use it to store linked geospatial data that changes over time and pose queries using two popular extensions of SPARQL.

Released 2010

Strabon's own publications page lists its earliest paper (naming Strabon explicitly) as a November 2010 SSN workshop paper at ISWC 2010; a second stRDF/stSPARQL paper from ESWC 2010 (May-June 2010) is listed in the same 2010 section. Used as the earliest documented year Strabon existed, since no separate software release date is published.

  • In Proceedings of 3rd International workshop on Semantic Sensor Networks 2010, in conjunction with ISWC 2010, November 2010, Shanghai, China.
