We will planned to digitalize occurrences from books. We were worked with department and we were included occurrences about rare species in oboth books (First book was about total list of flora of kurgans, second book was about rare species of region at different territories). So, some occurrences in both books include duplicate (not all, no). Bigger part of information include other occurrences. But we dont want to lose part of occurrences from second book (in this case it will look like incomplete part of book). We will want to made citations to second dataset from first published dataset and also save references from second book.
How I should do made refences on second dataset? Which one of solution is better? Reference to first dataset (or made it for duplicates from first dataset?)
Which one term of DwC is better to will use for reference of first dataset (or duplicates)?
Which one occurrence ID will be for duplicates?
Did You know examples of similar dataset`s?
I would be grateful for the answer
