The UML diagram below explains
why it is necessary to introduce the UML interface Element. When we introduce the
UML interface Discussion and define Discussion as the type of elements in DiscussionContainer,
we get the warning that this attribute is incompatibility with the inherited attribute
in ArtifactContainer that has the type Artifact. We corrected the problem by introducing
the interface Element as the type of the elements in ArtifactContainer.

Eric

Review Notes:
Based on
1.
Laura’s proposals http://www.oasis-open.org/apps/org/workgroup/icom/email/archives/201007/msg00021.html
and
2.
Eric’s suggestion to define generic concepts to
compose specialized concepts (see comments in http://www.oasis-open.org/apps/org/workgroup/icom/email/archives/201008/msg00000.html),
the following UML model was developed. Let’s review
the model:
Figure 1. Model of Forum
Figure 2. Model of Mailing List
In order to support the auxiliary class Discussion, it was
necessary to introduce another auxiliary class Element as a superclass of
Artifact. This was due to the UML and OO language issues.

superclass of Artifact
