Regarding underlying technology, the Semantic Trajectory Episodes Ontology Specification uses W3C's RDF technology, an open Web standard that can be freely used by anyone.
The Semantic Trajectory Episodes (STEP) is a lightweight ontology for representing semantic trajectories and contextual elements in terms of features of interests and episodes.
The template of this specification is derived from the FOAF Vocabulary Specification, which was created by Dan Brickley and Libby Miller, and the Ordered List Ontology, which was created by Samer A. Abdallah and Bob Ferris. It was modified by Tales P. Nogueira. Furthermore, a modified and extended version of Danbri's SpecGen version was used to generate most of the RDFa statements for this specification (see here for SpecGen version 6 by Bob Ferris).
For detailed information, please refer to the paper.
