Functions

extractDTKnowledgeGraph

fun AzureDigitalTwinState.extractDTKnowledgeGraph(dtUri: DTUri, dtSemantics: DigitalTwinSemantics): DTKnowledgeGraph

It extracts the DTKnowledgeGraph from a AzureDigitalTwinState of a dtUri, following its dtSemantics.

fun SignalRDigitalTwinUpdate.extractDTKnowledgeGraph(dtUri: DTUri, dtSemantics: DigitalTwinSemantics): DTKnowledgeGraph

It extracts the DTKnowledgeGraph from a SignalRDigitalTwinUpdate of a dtUri, following its dtSemantics.
