The document discusses using semantic web technologies and linked data to support real-time emergency response. It describes using an RDF triplestore accessed by agents to integrate data from various external sources and provide an overall picture to emergency responders through HTML5 apps. The system utilizes standard vocabularies and reuses existing linked open data to represent incident data, locations, addresses and other relevant information.

38. Why RDF?
 No clear overall picture  Open data ready
 Flexible model
 Multiple serializations
 Agile development
 Point to external data  Web technology
 Linked by definition  W3C Recommendation
