If data on the resource and data as the element in the record are:
- PoR/PaE–check the Data Entry instructions:
  - data for this element must be Recorded as a relationship: make sure the relationship is appropriate for the resource and verify Authorized Access Points against the LC/NACO Authority File
- PoR/AaE–check the Core instructions:
  - data for this element is NotCore:
    - if the data has been given as a wrong element, move it to the correct element
    - if the data is missing completely, add the data if you feel it might be useful–remember the principles of differentiation and sufficiency
