Create function to populate an Authority Source file ID

Context: Catalogers want a way to know the source of their authority records. They want a facet/filter that provides them the ability to only view records of the selected source or sources. This knowledge may prove important to our team in supporting the link between bibliographic records and authority records.'

Requirements

• When user imports an authority record Then we need to the check 001 or 010 $a for the identifying prefix (code). If the prefix (code) matches any of the values on the below tables THEN assign the record to a Source file.

• An authority record can only be assigned to one Source file

• Each identifying prefix (code) is unique and can be assigned to only one Source file (see list below)

• identifying prefix (code) is the "alpha value" of the 001 and 010$a

• identifying prefix (code) is case insensitive

• System should check if 001 has one of the prefixes (codes) below. If not then check 010 $a (all of them). If multiple $a with identifying prefixes (codes) then pick the first one. 

• If there is no prefix (code) OR the prefix (code) is not on the below list then assign to Not specified or not at all (whatever is easiest given additional requirements will support a user adding their own information to this list).

• Development should consider that additional rules will added to this implementation

• Each Source file can only be assigned to one Authority type (see below list)

Acceptance Criteria 

• No impact to mod-search performance. 

• Write Karate tests

• Given a MARC authority record is created via data import
  When 001 is populated
  AND the alpha prefix matches a value (i.e. n) on the Authority Source file list
  Then assign the record to an Authority source file (i.e. LC Name Authority file (LCNAF))

• Given a MARC authority record is created via data import
  When 001 is populated
  AND has no identifying alpha prefix that matches what is on the list
  BUT 010 $a does have an identifying alpha prefix that matches a value (i.e. n) on the Authority Source file list
  Then assign the record to an Authority source file (i.e. LC Name Authority file (LCNAF))

• Given a MARC authority record is created via data import
  When 001 is populated
  AND has no identifying alpha prefix that matches what is on the list
  AND 010 $a also does not have an identifying alpha prefix that matches what is on the list
  Then do not assign to an Authority source file

 Approach

• Extend MappingParameters with AuthoritySourceFiles field

• Create set_authority_source_file_id function that will be use in mapping rules to satisfy requirements
