As of jUCMNav 5.5, the XMI serialization of URN models (in .jucm files) uses identifiers (ID field) as pointers rather than XPath expressions, whenever IDs are available. For example:

<links xsi:type="grl:Decomposition" id="63" name="Decomposition63" refs="//@urndef/@specDiagrams.0/@connections.0" 
                                                                                     dest="//@grlspec/@intElements.0" src="//@grlspec/@intElements.2"/>

<links xsi:type="grl:Decomposition" name="Decomposition63" id="63" refs="//@urndef/@specDiagrams.0/@connections.0" dest="22" src="41"/>

because connections do not have IDs whereas intentional elements do.

The jUCMNav metamodel differs from the URN (Z.151) standard in a number of ways. See:

• Z.151 URN standard metamodel
• Key Differences between the standard metamodel and jUCMNav's.

• In Rational Rose (.mdl) format
• Documentation in HTML (for all browsers)
• Documentation in HTML (original applet-based Rose index, see WARNING
• All documentation as a ZIP file
• Note: Several colours for classes are used in this model:
  • Green: New in this version (since the last major release)
  • Blue: Interface
  • Yellow: Not used by jUCMNav at the moment
  • Pink: Deprecated
  • Additional comments identify deprecated attributes.

Failures (in package UCM.map)

• Added enumeration class FailureKind

• Added aggregation from FailureStartPoint to Condition

Responsibility bindings (in packages URNcore and UCM.map)

• Added new context attribute to Responsibility

Small modifications for better alignment with Z.151

• Added WaitKind enumeration (used by WaitingPlace)
• Added Xor to GRL DecompositionType.

-- Main.DanielAmyot - 29 Jun 2009

• Many modifications were done to clean the metamodel and align it with the draft URN standard.
• See http://jucmnav.softwareengineering.ca/twiki/bin/view/UCM/DraftRevisedMetamodel for details

-- Main.DanielAmyot - 15 Feb 2008

See also the discussions and changes to older URN metamodel versions.

A few things need to be considered when updating this metamodel:

• Multiplicities and (private) role names are required for all navigatable association ends
• Java data types for the attributes (Etienne seems to infer that Date does not work)
• All classes have to be included (aggregation) directly or indirectly in the URNspec class.

This is the metamodel (Rose file) used in the MSC export / MSC viewer based on the UCM scenario definitions and traversal mechanism.

Version 2 now has Metadata that can optionally be included in ModelElement objects.

• Scenarios2.mdl: UCM Scenarios Metamodel
• Documentation in HTML (for all browsers)
• Documentation in HTML (original applet-based Rose index, see <a href ="#WARNING">WARNING</a>)
• All documentation as a ZIP file

There has been reports that the original (Rational Rose) HTML version of these metamodels cannot be read properly by common browsers. One issue is that these files include a Java applet. Be sure that your JRE is compatible with your browser (i.e., 32-bit versions of IE9 and Firefox require a 32-bit Java Runtime Environment). If you have a 64-bit JRE, one option that works well is to use Waterfox.

In addition, you may have to adjust the settings of your Java environment (JRE security) to let the applet run, either locall, or from uOttawa:

1) Go to your Configure Java application:

2) Add http://www.site.uottawa.ca (or whatever site where the documentation is located):

3) When accessing the documentation, you will also need to let the application run:
