6. A Network of Knowledge
Digital Enterprise Research Institute www.deri.ie
 Interconnected
 Universal
 All encompassing
 assists humans,
organisations and systems
with problem solving
 enabling innovation and
increased productivity

7. Two Key Ingredients
Digital Enterprise Research Institute www.deri.ie
1. RDF – Resource Description Framework
Graph based Data – nodes and arcs
 Identifies objects (URIs)
 Interlink information (Relationships)
2. Vocabularies (Ontologies)
 provide shared understanding of a domain
 organise knowledge in a machine-comprehensible way
 give an exploitable meaning to the data
