Hi,
You'll have to extend the GenericDiffEngine (extension point
org.eclipse.emf.compare.diff.engine) so that its "getAttributesChecker"
method returns your own implementation. In this implementation, you can
ignore whatever attribute bothers you by overriding
"AttributesCheck.shouldBeIgnored(EAttribute)".

Hi,
There could be a number of reasons why your engine is not called :
1) you registered it against the wrong extension / namespace
2) you registered it against ecore with "lowest" priority (same as the
generic engine), thus the generic engine is called instead
You can work around 2) by either setting an higher priority or ticking
the option "Comparison engine selection" on the EMF Compare preference
page. If you're not calling EMF Compare from the Eclipse GUI, you'll
have to programatically set your own IMatchEngineSelector through
MatchService#setMatchEngineSelector() and IDiffEngineSelector through
DiffService#setDiffEngineSelector() so that they return your engines.
