If you open the metamodel browser, then you get a new command in the contextual menu, 'Check metamodel rules'. It opens an ORLintBrowser which runs over the browsed metamodel and check the classes. Currently there are 5 rules, 3 about Fame metamodel consistency, 2 about Famix conventions (those 2 are still a bit broken, dont take the results seriously).

We already fix some inconsistencies in Famix-Core, but it appears there are more in extensions of Famix.
