+The OMOC project studies mechanisms for the Ontology-based Management of Change.
 The idea is to manage dependencies in/between documents (given by document ontology). The
 target is  collaborative editing of mathematical documents (Plugin to Version Control).

-Computer support for document interaction is only possible, if some aspects of the meaning of the document content are made explicit - i.e. formalized and dealt with with formal methods. In many cases, useful services can be rendered by machines without having an entailment relation, for instance we can search for a formula, we can determine the concepts it depends upon, etc. The commonality of such services is that they are based on the structure of the formulae alone. For instance, instead of relying on a formal calculus to determine theorem-hood, we only insist that there be an object that has the structure of a proof.
