Where is Boundary stereotype in UML specification

[wings]

Hi, everybody,

I notice that I can not find any description about Boundary,Control and Entity stereotypes in UML specifications above 2.0 version.But they are all standard stereotypes, isn't it? So where can I find them in OMG site?

Thanks a lot.

That is because they are the EA equivalents of a very old pattern called "Model-View-Controller".  IIRC Boundary=View, Control=Controller and Entity=Model.  

They are quite handy, sometimes, when developing lower level models that involve a n-Tier architecture.

These days, the pattern (some would call it a paradigm) have got quite muddied.

The ECB is a pattern defined in the OpenUP
The stereotypes have never been standard UML, but in the 1.x specification these stereotypes were mentioned in a profile example.

Because of that a lot of case tool vendor have included those stereotypes in their product, but it is a common misunderstanding that these are (or were) UML standard stereotypes.

I think the MVC pattern is more like a specialization of the ECB pattern (specific to UI design). ECB can also be used in other areas.
