Adding taxon restrictions

Before adding taxon restrictions, please review the types of taxon restrictions documentation.

See Daily Workflow for creating branches and basic Protégé instructions.

  1. in taxon relations are added as Subclasses.
  2. Navigate to the term for which you want to add the only in taxon restriction.
  3. In the Description window click on the +.
  4. In the pop-up window type a new relationship (e.g. 'in taxon' some Viridiplantae).
  5. The taxa available are imported ontology terms and can be browsed just like any other ontology term.


  1. never in taxon or present in taxon relations added as Annotations.
  2. Navigate to the taxon term you want to add a restriction on.
  3. Copy the IRI (you can use command U to display this on a Mac)
  4. Navigate to the term for which you want to add the never in taxon restriction.
  5. In the class annotations window, click on the +.
  6. In the left-hand panel, select never_in_taxon or present_in_taxon as appropriate.
  7. In the right-hand panel, in the IRI editor panel, paste in the IRI.
  8. Click OK to save your changes.
  9. (Note - you can achieve the same thing using the Entity IRI tab + navigating to the correct taxon but this is slow and not very practical)
