We can more or less do this since we are already inserting labels into the
ontology in batch mode [1]. It would be quite helpful for us if someone
interested in editing the ontology programmatically, would produce a list
of changes (class name and changed properties, in any kind of machine
readable format you want, even Sparql would be nice). We could then better
experiment and introduce the changes directly into the mappings wiki.
Changing the ontology in the triplestore would create a synchronization
problem, by the next extraction those changes would need to be recomputed
and reintroduced.
Cheers,
Alexandru
