XML Topic Maps Processing Model 1.0 (XTMP) describes version 1.0 of a processing model for XTM that bridges the gap between the XTM abstract conceptual model and the XTM interchange syntax.

The XTM Processing Model defines the rules for processing XTM documents in order to map the meaning of the information they are intended to convey to their recipients. This processing results in topic map graphs that consist of nodes and arcs which connect the nodes.

The three kinds of nodes in a topic map graph are topic nodes (t-nodes), association nodes (a-nodes) and scope nodes (s-nodes). There are several arc types, and certain arc types can have labels.
