new to UML2 [message #476269]

Originally posted by: pfuriani.uci.edu

I have been looking for a way that UML Class Diagrams can be represented in
a universal way so that I can build a partial class diagram from it for my
plugin no matter what UML tool created the XMI for the UML Class Diagram.
UML2 seems like it can build more of a class diagram than I need so would
only be interested in using part of it. I first thought of XML Schema to
represent UML, however XML Schema lacks many things which are essential to
UML such as scope (private, public...) and a universal way to represent
operations and parameters (you can use annotations but everybody seems to
have their own way of using annotations). Does XMI support all the features
of a UML Class Diagram? I tried reading the specification but it left me
confused. I was referred to UML2 by a friend of mine who said I might be
able to use your XMI importer (if you have one) and then use the data that
was parsed from the XMI to build only what I need of the UML Class Diagram.
So, my main questions are:
1.) Does UML2 have such an importer to import an XMI file and parse class
diagram data from it?
2.) In XMI, is there really an accepted way that many of the UML Class
Diagram Generater tools out there that export to XMI use to represent all
the features of a UML Class Diagram (like operations, scope, parameters...).

Any help you can provide or answers to these questions would be greatly
appreciated. Thank you

Instances of the UML metamodel are represented in XMI using the UML2 API.
It uses EMF under the hood. So operations, parameters etc are serialized in
an XMI format.

- Try it out , create a simple .uml model with an operation, save it out and
open the file with a text editor.

I'm not sure if you are mixing ideas of 'notation' with 'semantics' in your
question. The opensource API does not support notation, the UML2Tools
project is concerned with notation and diagrams. So there is no importing
of diagrams with this UML2 API.

Cheers,

- James.

James,

Although he is talking about class digrams, I think what he's really
asking about is the underlying UML model that's being rendered as a
class diagram. I.e., he's not so much concerned about the diagram
itself, but rather extracting all the class, their associations, their
operations and so on. I think he should just read your introductory
material on how to create a UML2 instance using the basic UML editor...
