Hello,

we are creating our own model, which instances we want to compare. It's tree
based like Organization->Group->Person.
Each object is EMF based (we also have some .ecore file for it) and each
object has its own attribute values.
So we have model.ecore file as a meta-model.
And our model instances is saved in some xml format in multiple files. But
it doesn't matter I hope, because I want to do the comparison|merging of the
objects in memory.

What should we do when we want to use EMF compare project for comparing of
our EMF based model instances?

What should we implement? Do we need our structure and content viewers? And
what these viewers has as for interface needed?

Are there any steps to create COMPARE|MERGE editor for 2 model instances
(not only for 2 files, but models consisting of EObjects located in memory)
and visualized in Structure diff and merge viewer?

Thanks for any help.

BTW: Compare project looks very interesting and helpful for many scenarious.
It can be used for finding for example a diferences in a HIBERNATE MAPPINGS
FOR YOUR DATABASE. GOOD WORK :-) But I need some guide line to follow how to
extend it.

Best Regards,
Jan
