how semantic technologies supercharge a platform for context-aware applications
DESCRIPTION
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.TRANSCRIPT

Conclusions
• JSON-LD:– Developer-friendly– Facilitates integration
• Ontology as living documentation
• REST Linked Data
