Check the 'Source' instruction to be sure that you are looking at the correct source(s) of information on the resource
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 from a vocabulary (Open): make sure the term:
    - is appropriate for the resource
    - is either given exactly from the official list of terms for the element, except for capitalization (check for typos);
    - or conforms to the structure and reasoning of the official list (e.g., singular vs, plural), if it is a locally added term
- 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
- AoR/PaE–check the Source instructions again:
  - since the Source for this element is or includes 'Any', accept the data, but only if it seems applicable
- AoR/AaE–go to the next element:
  - but be sure to check the resource carefully, if the data for the element is Core, or if the data is important for differentiating the resource from a similar resource
