(as presented at GeoWeb 2009, July 30, 2009)

A new pillar of the web is RDF, a W3C supported technology to represent structured and unstructured metadata and to link very diverse data sets into a linked web of data. The geospatial community is starting to incorporate the same technology to model geospatial objects and annotate objects with metadata. The USGS National Map project being a great example.

As a provider of RDF based software and services, we see an increased interest from telecom providers, the transportation industry and defense integrators in tracking hundreds of thousands to millions of objects in real time. Consider fleets of trucks, swarms of airplanes, track data for soldiers on the (urban) battle field, track data for endangered animals, or location based services like Loopt.

In this presentation we will discuss and demonstrate the role of semantic technologies and performance considerations in developing these projects.
