How can model conflicts in hybrid wiki workspaces be solved collaboratively?

Ø  How does a meta-information model, which supports the collaborative solving, look like?

Ø  How would an algorithm for merging co-evolving EA models look like?

Ø  How can users be involved for the collaborative solving process?
