# Topology

Interface for reasoning structures

Layer: Infrastructure · Category: Data Structures

## Mechanism

A marker interface. A pattern implementing 'Topology' MUST declare the node-edge shape of the structure it describes — Linear, Tree, DAG, Cyclic and so on. The shape is the claim: it fixes what traversals and what orderings are possible, independent of what the nodes hold. Applies to any node-edge structure, not only to reasoning.
