I'm working on a standalone application. This application must load uml
files whose nsURI are http://www.eclipse.org/uml2/2.0.0/UML.

Is this nsURI indicates that i'm working on a UML 2.0 file ?

I try the code given by the article :
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_Guide/guide.html

I don't understand all. I want to know if my model to migrate must have
the extension .uml2 ? When I read this line :

extensionFactoryMap.put(UML22UMLResource.FILE_EXTENSION,UML2 2UMLResource.Factory.INSTANCE)

I assume that my file must be something like model.uml2 ? How can I
known if my file is a uml2.0 or a uml2.1 if the extension is wrong
(always .uml) ?

Hi David,

The resource handlers are registered against particular content type
identifiers so they should kick in regardless of the exension.
To determine the format of the model you can look at the serialized nsURI.
For example:
<uml:Model xmi:version="2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1"
xmlns:uml="http://www.eclipse.org/uml2/2.1.0/UML"
xmi:id="_UXe2UH6gEd2W3e_qmR_CeQ" name="m1">


Moving forward, the .uml extension will remain the same even as new versions
of UML come out. For example, the next version of UML is 2.2, however
the extension will remain .uml.

The migration guide you are looking at migrates from UML 1.0.0 to UML 2.0.0
(the extension changed here from .uml2 to .uml)
There was a second migration guide that migrates from UML 2.0.0 to UML 2.1.2
(the extension remains .uml)
The next migration will be from UML 2.1.2 to UML 2.2 - and introduces API
breaking changes ( a new migration guide will be posted ).

Cheers,

- James.

Presumably this should be "UML2 1.0.0" (ie the Eclipse plugin which
implemented something like UML 1.95) instead of "UML 1.0.0"

Thanks for your reply.

As I say in my previous post I'm working on a standalone app. I wan't to
load a UML 2.0.0 model (http://www.eclipse.org/uml2/2.0.0/UML).

When I do this, I have an exception that says : "Package with uri
'http://www.eclipse.org/uml2/2.0.0/UML' not found."

To fix this, I add the line
EPackage.Registry.INSTANCE.put("http://www.eclipse.org/uml2/2.0.0/UML",
UMLPackage.eINSTANCE);

This is the good way ? Or there is another solution ?

Hi Tom,

I was referring to the versions of UML as defined by OMG not the versions of
the plugins.
The versioning of the plugins do not align directly with the versions of the
spec.
The convention that we've tried to adhere to when referring to versions of
the spec at OMG is UML x.x.x, whereas when referring to versions of the
plugins we use UML2 x.x.x.

For example, the next version of UML (OMG spec.) will be UML 2.2 whereas
the corresponding plugin version will be UML2 3.0.0.

Also, the version of UML 2.1.2 is implemented in plugins starting from UML2
2.0.4 all the way to UML2 2.2.

It's a bit confusing since the versions of the plugins seem to align closely
to the versions of the spec but that is coincidental.

Cheers,
- James.

Thanks for the clarification James, but now I'm more confused than ever.

Your original message said:

>> The migration guide you are looking at migrates from UML 1.0.0 to UML
>> 2.0.0 (the extension changed here from .uml2 to .uml)

Since you referenced file extensions (.uml2 & .uml) and I was pretty
sure that the UML2 plugin never implemented UML 1.5 or any of the
earlier UML 1.x versions, I just jumped to the conclusion that you were
talking about UML2 versions instead of UML versions.

Your clarification said:

> I was referring to the versions of UML as defined by OMG not the versions of
> the plugins.

Is there actually a migration guide which describes migrating from UML
1.x (say UML 1.4 or UML 1.5) to UML 2.x using the Eclipse UML2 plugin?

That would be a great resource for me. Could I get a pointer to it?

This statement is a mistake:
The first migration guide
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_Guide/guide.html
indicates migration from the UML2 1.x API based on the UML 2.0.0 interim
draft specification to UML2 2.0 API based on the UML 2.1 specification.
At this time the extension changed from .uml2 to .uml.
Major changes to the spec were introduced at this stage (and the major
version number of the API was changed).

No, unfortunately not. However, the changes between UML 1.x and UML 2.x
(OMG spec. wise) would be substantial and difficult to document I would
suspect.

OK, now we're on the same page. I was just trying to correct the typo
so that no one would get confused, but just managed to inject more
confusion.

Yes, I'm sure you're correct, but just imagine how much harder the
migration will be without this information. That's the situation we're
facing as we migrate to the UML 2.1.x (via the UML2 plugins).

It's unfortunate that the OMG has never felt the need to document the
differences between one version and the next -- or better yet, maintain
backward compatibility!

Hi Tom,

The OMG maintains "change ballots" that describe differences between the
various versions of the spec., however, these change ballots are complex in
themselves.
The OMG also produces versions of the spec with "change bars" that indicate
areas that have changed.
Your best bet might be to try and locate those change ballots or compare the
specs. with change bars.

Good luck.

- James.

The change ballots aren't really all that complex, but you do need to go
back to original issues in the issue database to get an understanding of
what the change was.

I've been following the OMG's activities for years and have never come
across a change-barred version of the UML 2.0 spec which contained the
changes that were made between UML 1.5 and UML 2.0.

I'd love to get a pointer if you (or anyone else) has one.

Hi David,

The resource handlers are registered against particular content type
identifiers so they should kick in regardless of the exension.
To determine the format of the model you can look at the serialized nsURI.
For example:
<uml:Model xmi:version="2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1"
xmlns:uml="http://www.eclipse.org/uml2/2.1.0/UML"
xmi:id="_UXe2UH6gEd2W3e_qmR_CeQ" name="m1">


Moving forward, the .uml extension will remain the same even as new versions
of UML come out. For example, the next version of UML is 2.2, however
the extension will remain .uml.

The migration guide you are looking at migrates from UML 1.0.0 to UML 2.0.0
(the extension changed here from .uml2 to .uml)
There was a second migration guide that migrates from UML 2.0.0 to UML 2.1.2
(the extension remains .uml)
The next migration will be from UML 2.1.2 to UML 2.2 - and introduces API
breaking changes ( a new migration guide will be posted ).

Cheers,

- James.

Presumably this should be "UML2 1.0.0" (ie the Eclipse plugin which
implemented something like UML 1.95) instead of "UML 1.0.0"

Thanks for the clarification James, but now I'm more confused than ever.

Your original message said:

Since you referenced file extensions (.uml2 & .uml) and I was pretty

earlier UML 1.x versions, I just jumped to the conclusion that you were
talking about UML2 versions instead of UML versions.

Your clarification said:

Is there actually a migration guide which describes migrating from UML
1.x (say UML 1.4 or UML 1.5) to UML 2.x using the Eclipse UML2 plugin?

That would be a great resource for me. Could I get a pointer to it?

This statement is a mistake:
The first migration guide
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_Guide/guide.html
indicates migration from the UML2 1.x API based on the UML 2.0.0 interim
draft specification to UML2 2.0 API based on the UML 2.1 specification.
At this time the extension changed from .uml2 to .uml.
Major changes to the spec were introduced at this stage (and the major
version number of the API was changed).

.... sorry about the confusion.

No, unfortunately not. However, the changes between UML 1.x and UML 2.x
(OMG spec. wise) would be substantial and difficult to document I would
suspect.

OK, now we're on the same page. I was just trying to correct the typo
so that no one would get confused, but just managed to inject more
confusion.

Yes, I'm sure you're correct, but just imagine how much harder the
migration will be without this information. That's the situation we're
facing as we migrate to the UML 2.1.x (via the UML2 plugins).

It's unfortunate that the OMG has never felt the need to document the
differences between one version and the next -- or better yet, maintain
backward compatibility!

Hi Tom,

The OMG maintains "change ballots" that describe differences between the
various versions of the spec., however, these change ballots are complex in
themselves.
The OMG also produces versions of the spec with "change bars" that indicate
areas that have changed.
Your best bet might be to try and locate those change ballots or compare the
specs. with change bars.

Good luck.

- James.

The change ballots aren't really all that complex, but you do need to go
back to original issues in the issue database to get an understanding of
what the change was.

I've been following the OMG's activities for years and have never come
across a change-barred version of the UML 2.0 spec which contained the
changes that were made between UML 1.5 and UML 2.0.

I'd love to get a pointer if you (or anyone else) has one.
