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.
