UML meta-levels mapping in Eclipse [message #478128] Mon, 19 January 2009 16:56 Go to next message

Hi All,

I have some confusion in understanding the UML meta levels in Eclipse. I
have created a new project in UML's component diagram. Does it represent
the UML meta level 2 (M2) or meta level 1 (M1). Is there any article that
can explain how the UML's meta level are mapped in Eclipse MDT and Eclipse
UML tools?

Any hint in defining a project at M2 level, extending it in M1 level and
creating instances at M0 level?

Thanks
Waqas

Hi Waqas.

* The M2 level represents the metamodel level. The eclipse UML2 project is
an implementation of the UML metamodel. The UML2 project does not involve
diagrams at all.

* M1 represents the Model level. When you are modeling using UML2Tools you
are creating instances of UML meta-types. For example when you create a
class called "My Class" what you are creating is an instance of the
uml:Class metatype from M2 level.

* M0 describes Instance level.

I'm not sure what you mean when you say: "I have created a new project in
UML's component diagram". Do you mean that you are extending UML in some
way?

This article might be of some use:

Cheers,
