- MARC-MARC matching
- Lotus: Allows for any field in a MARC record except
- Are these needed in Morning Glory?
- Matching for 100-899 fields? (I think they work, but not heavily tested yet)
- Repeatable fields (e.g. 024, 035)
- Incoming record: Only first version of the field is considered (doublechecking with the dev on whether it's the first field that has the requested indicator(s) and/or subfield, or just the first field, regardless of indicators/subfield)
- If it takes Ind 1, Ind 2, Subfield into account (in addition to the data)
- Does FOLIO need to check all incoming 024s against all 024s in the existing SRS records? Or just the first?
- Wildcards for Ind 1, Ind 2, Subfield (repeatable or non-repeatable fields)
- Needed?
- Additional info from A-M/Igor:
Let's pretend that these fields are in an incoming record: (Field Ind1 Ind2 Subfield)
- 024 _ _ $a 12345
024 1 1 $a 45678
024 1 _ $x 67890
024 2 2 $x 67890
- 024 _ _ $a 12345
And the fields in the existing SRS record are
024 2 2 $x 67890
024 _ _ $a 12345
024 1 _ $x 13579
024 1 1 $a 45678
024 1 _ $x 67890
I understand that for repeatable fields, FOLIO Lotus only pays attention to the first incoming field, not the rest, but compares to any matching fields in the existing record.
Now - setting up different match profiles, I want to be sure I understand the logic that is in place now:
If the match profile is 024 _ _ $a:
- Matches, because the incoming first 024 looks for an existing 024 with blank indicators and $a and the same value (even though that is the second 024 in the existing record)
If the match profile is 024 1 1 $a:- Matches, because the first incoming 024 with indicators 11 and $a (which is the second 024 in the incoming file) looks for an existing 024 with indicators 11 and $a and the same value (which is the fourth 024 in the existing record)
If the match profile is 024 1 _ $x:- Matches, because the first incoming 024 with indicators 1_ and $x (which is the third 024 in the incoming file) looks for an existing 024 with indicators 1_ and $x and the same value (which is the fifth 024 in the existing record)
If the match profile is 024 2 2 $x:- Matches, because the first incoming 024 with indicators 22 and $x (which is the fourth 024 in the incoming file) looks for an existing 024 with indicators 22 and $x and the same value (which is the first 024 in the existing record)
- However!
Let’s pretend the incoming record looks like this:- 024 1 1 $a 12345
024 1 1 $a 45678
- 024 1 1 $a 12345
- And the existing SRS record is
- 024 1 1 $a 45678
- If the match profile is 024 1 1 $a, SRS does not match, even though “024 1 1 $a 45678” is present in both incoming and existing records.
SRS starts searching a field, that is specified in match profile, scrolling the incoming record from the very beginning, as usual, and takes the first occurrence of <024 1 1 $a>. The first occurrence is “024 1 1 $a 12345". So, SRS takes “024 1 1 $a 12345” and can’t find it in the existing record
