KNOWLEDGE AGENT

Term	Description	Comment
Knowledge Graph	A semantic graph, representing real data	Describes relation between subjects and objects
Knowledge Agent	Components to operate on knowledge graphs across the dataspace	see Agents KIT
Matchmaking Agent	Resolves federated sub-graphs for the Knowledge Agent	Fits requested sub-graphs with existing graph assets
Binding Agent	A component that binds instances to the knowledge graph	Binds instances of data or services to the knowledge graph
