-- Topic Maps -- Part 2: Data model
ISO/IEC 13250-2:2006 specifies the Topic Maps data model. It defines the
abstract structure and interpretation of topic maps, the rules for merging
topic maps and a set of fundamental subject identifiers. The purpose of the
data model is to define the interpretation of the Topic Maps interchange
syntax, and to serve as a foundation for the definition of supporting standards
for canonicalization, querying, constraints, etc.
