gst-Store: An Engine for Large RDF Graph Integrating Spatiotemporal Information
Dong Wang, Lei Zou, Dongyan Zhao · 2014
In this paper, we present a spatiotemporal information integrated RDF data management system, called gst-Store. In gst-Store, some entities have spatiotemporal features, and some statements have valid time intervals and occurring locations. We introduce some spatiotemporal assertions into the SPARQL query language to an-swer the spatiotemporal range queries and join queries. Some ex-amples are listed to demonstrate our demo.
