- Collection-level level attribute*
- Collection-level title*
- still need to test how the importer handles multiple title elements
- still need to test how the importer handles multiple title elements
- Collection-level date*
- can occur within did/unititle
- Collection-level identifier*
- Collection-level extent statement* (but may need to be tested differently)
- Component-level level attribute*
- Component-level title OR component-level date*
- If there's the a level attribute = set to 'otherlevel', then the otherlevel attribute must be set*
- Normalized unitdates
- must be valid dates (e.g. 2015-02-30 will probably raise an error, but still need to verify this)
- the end date cannot occur before the begin date (but the end date can equal the begin date).*
- No more than 3 container groups per level of description
- (should we also ensure that container elements have id attributes and parent attributes, or can we just go ahead and change the importer so that it only uses these values when they're present in the EAD source files??? i.e. if not id and parent attributes, then assume that all sibling container elements constitute the same group.)
