| <h2>Introduction</h2> |
| |
| <p>The underlying motivation behind metamodel changes in the UML2 2.1 release has |
| to do with fixing problems that were discovered while trying to implement |
| redefinition, however, there are more fundamental problems regarding the impact |
| that bidirectional associations in the metamodel have on modeling in practice.<span |
| style='mso-spacerun:yes'> </span>The bidirectional associations in question |
| are the ones between Transition and Vertex specifying incoming/outgoing and |
| source/target, and also, the one between <span class=SpellE>ConnectorEnd</span> |
| and Connector specifying ends and roles ( refer to: <i><span style='color:black'><ins |
| cite="mailto:Bran%20Selic" datetime="2007-04-05T10:33">Superstructure |
| (ptc/07-02-05)</ins>, </span></i>p.164 <ins cite="mailto:Bran%20Selic" |

| |
| <p>These associations make practical use of the API/metamodel difficult since |
| for example changing the source or target of a transition in a specializing |
| context would cause the incoming/outgoing of a vertex in some other context (and |
| possibly different model/resource) to be updated.<span |
| style='mso-spacerun:yes'> </span><span lang=EN style='mso-ansi-language:EN'>The |
| purpose of these changes was to break the requirement for bi-directional |
| associations to not directly modify the incoming and outgoing properties of |
| Vertex which could be in another model.<span style='mso-spacerun:yes'> </span><o:p></o:p></span></p> |
| |
| <p>These changes were incorporated into the metamodel in anticipation that |
| changes would be adopted in the 2.2 specification that as of this writing has |
| not yet been finalized.<span style='mso-spacerun:yes'> </span>The metamodel |
| changes require changes to the serialized representation on disk thereby |
| requiring a change to the namespace URI. </p> |

| <h2>Understanding the issues
</h2> |
| |
| <p>Prior to UML2 2.1, in order to create a connector between connectable |
| elements (which could be in different resources), the connectable elements (and |
| hence the resources that contain them) need to be modified. Likewise, to create |
| a transition between vertices, the vertices need to be modified.<span |
| style='mso-spacerun:yes'> </span>The properties at the end of these |
| bidirectional associations need to be made derived in order to enable practical |
| use of connectors and transitions in an application that supports redefinition |
| and/or team scenarios. Specifically, properties <span class=SpellE>ConnectableElement::end</span>, |
| <span class=SpellE>Vertex::incoming</span>, and <span class=SpellE>Vertex::outgoing</span> |
| should be made derived.</p> |
| |
| <p>Until similar changes are made to the UML specification (e.g. as part of UML |
| 2.2), export to XMI interchange format will serialize the (otherwise transient) |
| values of these derived features so as to maintain compliance with UML 2.1.1.</p> |
| |
| <h3><o:p> </o:p></h3> |
| |
| <h3>Regarding the bidirectional association between Vertex and Transition:</h3> |
| |
| <p>UML RTF issue 10537 (<a |
| href="http://www.omg.org/issues/uml2-rtf.html#Issue10537">http://www.omg.org/issues/uml2-rtf.html#Issue10537</a>) |
| addresses the problem which can be summarized with the following example</p> |
| |
| <p><i style='mso-bidi-font-style:normal'><u>Example<b>:<o:p></o:p></b></u></i></p> |
| |
| <p>In context C1, assume we have 3 states S1, S2, S3 and a transition T1 from |
| S1 to S2.<span style='mso-spacerun:yes'> </span>Context C2 <span class=GramE>specializes</span> |
| context C1.<span style='mso-spacerun:yes'> </span>C2 redefines T1 call it |
| T1*.</p> |
| |
| <p><i style='mso-bidi-font-style:normal'><u>Issue:<o:p></o:p></u></i></p> |
| |
| <p>Assume we want to change the target of T1* to S3.<span |
| style='mso-spacerun:yes'> </span>S3 itself is not redefined, but rather, |
| visible through inheritance.<span style='mso-spacerun:yes'> </span><span |
| class=GramE>By changing the target of T1* to S3 we are actually referring to |
| the S3 in the context of C1 and thereby crossing model boundaries.</span><span |
| style='mso-spacerun:yes'> </span>This is a result of a bi-directional |
| association between Vertex and Transition in the meta-model.</p> |
| |
| <p><i style='mso-bidi-font-style:normal'><u>Resolution:<o:p></o:p></u></i></p> |
| |
| <p>The resolution involves breaking the bidirectional associations into two |
| unidirectional associations.<span style='mso-spacerun:yes'> </span>In this |
| way, when we wish to change the source/target of a transition, we do not |
| directly modify the incoming and outgoing properties of Vertex.</p> |
| |
| <p>The following modified metamodel diagram captures the changes:</p> |
