Reuse of CHEBI ontology terms within CDNO
Where possible the IDs, labels and definitions from the Chemical Entities for Biological Interest (CHEBI) ontology were reused in CDNO, however hierarchies that were not thought relevant in the nutrition domain for CDNO, had to be removed from the CHEBI OWL file importing solely a list of required terms and classifications to be reused.
