This page contains the URN/Z.151 metamodel (version 2, October 2012) in a form compatible with the Z.111 standard meta-metamodel and independent from jUCMNav's implementation. The jUCMNav metamodel differs from the URN (Z.151) standard in a number of ways. See:

Classes in gray and their associations and attributes are part of the concrete syntax metamodel, whereas the classes in white are part of both the abstract syntax and concrete syntax metamodels.
Diagrams whose names end with Abstract are for the abstract syntax metamodel, whereas those that end with Concrete extend the abstract syntax metamodel with additional classes and relationships (associations, inheritance, and aggregations) to produce the concrete syntax metamodel.
Diagrams whose names end with Unused are not being used in the Z.151 URN standard document; they are just included for information.
