Relationship between UML and a custom model [message #477818]

Hi all,

one question concerning the relationship between an UML and my own model. I
merged the whole kernel package from the UML Superstructure into my own
model, let's call it XModel. In that XModel i defined a package foundation,
which takes all the elements from the Kernel package. Now, i have a more
conceptual, theoretically question:

When i want to transform a uml class model into my XModel, is it sufficient
to copy the parts of the containment tree from the uml model into my XModel?
Or more precisly, how do the elements in the UML::kernel and
XModel::foundation relates to each other? IMHO, they only mutuality of them
are their names. They are not compareable to each other in a conceptual way,
because the are defined in different model scopes, aren't they?

Thx
Timothy

hi,

the problem in this case would be that the *.uml model is based on the
merge product of the whole UML superstructure, and not only the kernel
package. Thus, such a .uml model may contain information that is not
present in your merged subset and/or be incompatible with it.

Hi,

yes, that's clear. Let's assume, that i want to copy only elements from the
kernel package, for example, a package with classes inside. Are they still
compatible or does they only have identical naes, but are logical disjoint?

Thx

Tomothy,

You're right, there's no explicit relationship between the merged results.
The original idea was that the two versions of "Class" could be treated in a
similar way by a tool if one namespace were mapped in some way (e.g. by
using a schemaLocation attribute) to the other; the assumption was that
tools could process features (XML elements and attributes) that they
recognized and simply ignore ones they didn't. But there seems to be some
interest of late (even within the OMG) in understanding the heritage of a
given merged element and using that information to determine the
"compatibility" of different "flavours" of the same class...

Oops, sorry for the typo in your name, Timothy. :(
