Knowledge Model

Declare meaning, containment, and relationships independently.

Ontology specifies the kinds and fields a corpus permits. Topology specifies containment and tier shape. A graph consists of actual nodes and edges, with declared sources and readers. These axes are orthogonal: a graph can be structurally valid yet semantically invalid, or the reverse. Conformance compares authored declarations to instances in both directions.
