Hi Alain,
EMF does work without extension points, but in its current state
needs manual registration of you EPackages.
Ok that is the interesting part.
The OSGi Compatibility option in the genmodel only defines the
org.eclipse.core.runtime as optional, which dues does not really
solve anything.
Agreed, not much.
You can run EMF e.g. in an non-OSGi/non-Eclipse environment as well. No
matter where, you only need org.eclipse.emf.common,
org.eclipse.emf.ecore and org.eclipse.emf.ecore.xmi as dependencies.
As Jürgen told, the required bundles declaration in the manifest defines
the org.eclipse.core.runtime dependency as optional.
We have an extension for EMF that solves this issue. You can have
EMF with any framework you like and without extension points. Have
a look here: https://gitlab.com/gecko.io/geckoEMF
Gitlab is reporting an error " An error occurred while loading commit
signature" and not getting that error with the other gecko.io
<http://gecko.io> project.
Thats a little bit strange, I will check this.
You can also try the artifacts from the links in the project description
readme.md
If you have any questions, feel free to ask.
Jürgen.

I would expect that Mark Hoffman or Jürgen Albert might have
some useful pointers, I’m pretty sure that they’re heavy users
of EMF.
Best Regards,

Scott,
I noticed the split of the o.e.core.runtime and am already
using the o.e.equinox.common + supplement and running some
stuff like that with Felix. But that part doesn't include of
the support for extension points that is in the other "half",
hence my question.

Yes wrt extension registry/extension points.
o.e.core.runtime is a split package, split between bundles
o.e.equinox.common and o.e.equinox.registry
I'm not sure of the justification for split packages, but I
think it was
done to maintain backward compatibility in eclipse plugins.
The version I used was a few years ago, but at that time
these two
bundles...along with equinox...would run the extension
registry (i.e.
process extension points/extensions on startup). AFAIK
that's still the
case.
If you want to use a framework other than equinox, I know
for certain
that o.e.equinox.common works just fine on Felix...as long
as one also
includes this bundle [1].
I don't think EMF requires anything in addition to
o.e.equinox.common
and o.e.equinox.registry but I'm not completely sure about
that.
