  We consider ontology evolution in a system of light-weight Linked
  Data ontologies, aligned with each other to form a larger ontology system. When
  one ontology changes, the human editor must keep track of the actual changes and
  of the modifications needed in the related ontologies in order to keep the system
  consistent. This paper presents an analysis tool MUTU, by which such changes
  and their potential effects on other ontologies can be found. Such an analysis is
  useful for the ontology editors for understanding the differences between ontology
  versions, and for updating linked ontologies when changes occurred in other
  components of an ontology system.},
