This presentation highlights some of the ways in which Argus Labs uses semantic technologies to power Jini, its platform to enable context-aware services in third-party applications.
Ontologies, JSON-LD and Linked Data principles all work together to create a flexible system with a powerful RESTful API for situational understanding.

Presented in the Industry Track at the International Semantic Web Conference 2013, Sydney, Australia.
