How to implicitly import an XMI resource ? [message #703447]

Hi,

I have created my metamodel with primitive types (int, string, etc.) and constructed types (struct, tuple, array, etc.)
The choice I've made is to have a single PrimitiveType (meta)class and to define my primitive types as instances of this class. currently I store them in an XMI file.

I have also developed a parser for a language associated with this metamodel. But obviously, without proper support, the XMI file isn't known to the parser while this should be transparent to the users. So I am wondering:

What's the proper way to have my XMI file implicitly included in any user source ?

Regards,
Julien

Hi,

the keyword is ResourceServiceProvider, but it would be helpful
if you generate an editor for the metamodel too,
so that the xmi files have an .xyz extension and not a .xmi

Ok, thank you for the info!

Regarding the generation of a metamodel editor, I didn't do it.
Instead, I have set the Model.FileExtension and defined Model.ResourceType to "XMI". It seems to me this is enough to allow loading the model from a file with an extension. I don't think I need to generate an editor for a single file that's not expected to need any change.

Hi,

just as some background info: the resourceserviceprovider is bound to the file extensions so .xmi may be a bad idea

I guess I wasn't specific enough.
I did set the ResourceType to "XMI", but the FileExtension to something else ("xhla" in my case.)
If I understand correctly, this actually means that the content of the file will be XMI but that the expected (and thus loaded) extension is .xhla
