Ho everybody, Marcos.
Im trying to extend your AMWtoATL_Match.atl HOT transformation so that
it takes two inputs besides the AMW file, and one output (similar to the
"Merge of geographical information and statistical data" use case). I
will also add some new kind of links. For that I defined one MMW
extension, based on mw_base_extension.km3, and made a very simple
weaving model. So far so good.
However, for trying out the HOT transformation, I need an '.ecore'
metamodel to which the weaving model corresponds (to specify it as the
"AMW metamodel" in the launch configuration, am I right?). That's where
the problems start.
I tried "Inject KM3 into Ecore Metamodel" with my first extension with
no luck: the mw_base_extension.km3 classes weren't found, I could not
register those classes in the repository due to lack of namespace and
URIs, etc. Therefore I decided to include in my extension file the
packages contained in the mw_base_extension.km3 extension. That was
enough to take away the errors reported when generating the ecore. So
now I got an extension file and a metamodel in ecore format representing
it. Next I tried to make a new weaving model based on this new extension
file, so I could run my HOT on it. Regretfully, when I use the wizard to
create a new weaving model, and load this extension, I keep getting
"Class WXXX is not extended", where class WXXX can be WLinkEnd,
WModelRef, etc. (any of the ones defined by the base extension).
The problem is that all the classes have not-abstract extensions defined
in my file. I tried to versions of it: copying the mw_base_extension.km3
elements into my own package, or copying them into my file but keeping
them in their own packages (both versions attached). It didn't work.
Am I doing something wrong?, please help me, as this prevents me from
testing the HOT transformation, and it's holding me up.
Thank you in advance, and best regards,
Juan Pedro
