Field 580 Linking Complexity Note needs a type

[kirkhess]

The mapping for 580 Linking Complexity note doesn't have a specific note type, so if you convert back to MARC all 580s are converted to 500 fields.

The 580 is extensively used by CONSER, and is documented in the CCM, specifically module 14 https://www.loc.gov/aba/pcc/conser/CCM/Module14.pdf. The module goes through the specific situations for CONSER to use the 580 note, and it doesn't equate 500 and 580.

The simple solution is to add a note type for Linking Complexity in the Note ontology.
