Could you build this?
Partial A visual diff UI and basic RDF/JSON graph comparison are buildable, but meaningful semantic diffs of ontologies (IRI renames, blank nodes, OBO semantics) require domain knowledge and nontrivial graph-matching algorithms.
What it would actually take: Use an RDF library (such as rdflib or Jena) and a graph-diff algorithm, then add a visual diff front end. The hard part is matching nodes across versions and interpreting OBO and ontology semantics, which needs knowledge-engineering expertise and careful algorithm design.
