The fact that two nodes have the same subject must be detectable in order to trigger the merging operations that transform a well-formed topic map graph into a fully merged one. Therefore, at least one property of every node must be defined by its governing TM Application for the express purpose of allowing the subject of the node to be distinguishable from all other subjects, and in order to allow the subjects of nodes, when they are identical, to be recognizable as identical by the topic map graph merging process. Such properties are called "Subject Identity Discrimination Properties" (SIDPs). The values of SIDPs, and no other data of any kind, are used in TM Application-defined calculations to determine whether any two nodes should be merged.
The fact that two nodes have the same subject must be detectable in order to trigger the merging operations. Subject identity is determined on the basis of all the SDPs values possesed by a node.
Recall, defining properties of nodes and not how they acquire them
at this point.

Note: SDPs are set by the governing TM Application, which is required to specify at least one SDP for every node. See, Defining TM Applications. REF: parid0961 TXT: Subject identity is the values of SIDPs
