| Description | The Abstract Knowledge Graph defines the top level constructs of Entitys and Relations which have no spatiotemporal extension and do not participate in composite structures.. Most "data models" function as Abstract Knowledge Graphs, offering limited semantic expressivity. In SysFEAT, Abstract Knowledge Graphs are used to define all syntactic constructs required for model management, including Packaging and Annotation (see Annotation Block). Full semantic capabilities are provided by 4D Composite Knowledge Graphs. |
