A Heuristic Level Identifier (HL ID or HLID) is a compact string that externally identifies data objects in the KB.
- Heuristic Level means that the HL ID is based on the heuristic level rather than the epistemological level.
- Compact means that the HL ID is shorter than the GUID for the same data object.
- External means that the HL ID is the same across all Cyc instances.
