How do I get .emx recognised as .uml2? [message #474200]

Dear All,

We get passed .emx files from a supplier which are created in Rational
version 6.

They are .uml2 files.

We are using the compare tool to compare the current design to a new one.

At the moment all the users have to copy the .emx files as .uml2 and
then open them at which point the .uml file is auto-created.

Is there anyway in which I can tell the UML/EMF subsystem that a .emx is
a .uml2 & that it should simply open a .emx as a .uml2 & thus
auto-create the .uml file as this would remove what most of my users see
as an unnecessary step?

TIA

Adam

Adam,

A .emx file is not a .uml2 file - the .emx file format is a superset of the
..uml2 file format. A .emx file may contain elements (e.g. diagrams) that
cannot be recognized by the open source UML2 implementation, and will also
reference profiles and perhaps model libraries that are specific to
Rational. Also, .emx files (from RSx 6.x) use an enhanced cross-document
reference format that can't be handled by any of the EMF-based open source
resource implementations. If you want to load a .emx file, you're better off
using the APIs provided by Rational to do so, or exporting the models to
..uml2 format using the exporter provided by RSx.

Having said that, you can register the open source UML2 resource
implementation against a different extension using code similar to this:

resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put( "emx",
UML2Resource.Factory.INSTANCE);

Hi Adam,

Whey you say "[emx files] are .uml2 files", this is not true. .emx's handle
hrefs differently and also are composed of a notation metamodel. I would
not recommend doing what you are proposing, but, if you want to ...

Have a look at org.eclipse.uml2.uml.editor in the manifest. the extension
org.eclipse.ui.editors have a list of understood extensions. If you simply
add .emx there then the uml editor will attempt to open up .emx's.

Let me know if you run into other issues.

Regards,

- James.
