Manuall created records
Dear all,
I want to create records manually, and i am using MARC::Record to do
this. Records come out but they are not accepted by e.g. Zebra due to
some strange reason. I have been talking with some guys over on the
Zebra list, and they seem to be of the oppinion that the fault lies in
the MARC record.
Here is shortly my test setup:
I have the following Perl script to generate the test MARC record:
-
#!/usr/bin/perl -l
use MARC::Record;
use MARC::Lint;
$marc = new MARC::Record;
$lint = new MARC::Lint;
$field_001 = MARC::Field-new('001', '01');
$field_003 = MARC::Field-new('003', 'REALNODE');
$field_005 = MARC::Field-new('005', '20031015153536.0');
$field_100 = MARC::Field-new('100','1','','a' = 'Test Author');
$field_245 = MARC::Field-new('245','0','0','a' = 'Test Title');
$marc-append_fields(($field_001, $field_003, $field_005, $field_100,
$field_245));
open OUT, 01 or die($!);
print OUT $marc-as_usmarc();
close OUT;
$lint-check_record($marc);
print join( \n, $lint-warnings ), \n;
I have this script saved as test.pl, and when running it, i get no
errors, even though i have the Lint-function in MARC::Record in use.
[EMAIL PROTECTED] perl]$ ./test.pl
[EMAIL PROTECTED] perl]$
Here is the formatted output of the MARC record using the marcdump
script supplied with MARC::Record:
[EMAIL PROTECTED] zebra]$ marcdump temp_records/1
temp_records/1
LDR 00154 00085
001 01
003 REALNODE
005 20031015153536.0
100 1 _aTest Author
245 00 _aTest Title
Recs Errs Filename
- -
1 0 temp_records/1
[EMAIL PROTECTED] zebra]$
However, when updating Zebra to index the newly created record, it does
not accept this and returns the following 'error':
15:44:11-15/10: zebraidx(3122) [log] Zebra version 1.3.10 $Date:

i.e. Zebra treats the record as being empty.
I attach the raw MARC file (1) if it helps anyone. All hints are
most welcome, since i am getting fairly lost with all different
oppinions, since i am no MARC expert.
Thanks in advance!

Re: Manuall created records
Christoffer, i.e. Zebra treats the record as being empty. 00154 00085 0010011000300090001100500170002011600037245001500053 01 REALNODE 20031015153536.0 1 aTest Author 00 aTest Title The record isn't strictly correct as the Indicator count and Subfield code length are both blank (character positions 10 and 11.) MARC21 says these should always be set to 2. Also the Lenght of length-of-field, length of starting-character-position and length of implementation-defined (positions 20, 21, 22) should also be set to 4, 5, and 0 respectively. Position 22 should also be 0. Also the character at position 25 should be the field terminator character, not a blank. So, I think your record should look like: 00154 2200085 450 0010011000300090001100500170002011600037245001500053 01 REALNODE 20031015153536.0 1 aTest Author 00 aTest Title If an application such as zebra is doing things correctly, then it has every right to think the record is bad if it sees these errors. Of course, it may be something else completely.

Position 22 should also be 0. Thanks for the details Ashley. When building a MARC record, and the leader is not specified with the MARC::Record::leader() method, then a minimal leader is built, with an autopopulated record length (positions 0-4), and base address of data (positions 12-16)...but that's it. I've entered a bug [1] in to rt.cpan.org indicating that the autopopulation should also add other MARC21 defaults as specified here [2] Chritoppher, for the time being (ie. until he method is fixed) you can always specify the leader yourself and include the positions that Ashely mentions. ## build leader piecemeal my $ldr = ' ' x 24; substr( $ldr, 10 ) = 2; substr( $ldr, 11 ) = 2; substr( $ldr, 20 ) = 4; substr( $ldr, 21 ) = 5; substr( $ldr, 22 ) = 0; $r-leader( $ldr ); It would be interesting to know if this was what was throwing Zebra. Thanks very much for posting to the list, and let us know if there are any more developments. A new MARC::Record should be available soonish. //Ed [1] https://rt.cpan.org/Ticket/Display.html?id=4113 [2] http://www.loc.gov/marc/bibliographic/ecbdldrd.html Hello again. After addding the new information into the leader specified by Ashley and using the code snipplet from Ed (however adding the third argument into substr) i got a record that was accepted by Zebra. I will experiment more on the subject, and will most certainly appear here again if i run into trouble. The character at position 24 which according to Ashley should be a field terminator instead of blank, did apparently not affect Zebra. I do not know if this is good or bad (Zebra too sloppy or Ashley too strict...=) but for the time being, it seems to work. Btw: there seems to be some subfields that are valid but have not been entered into MARC::Lint since they according to http://www.loc.gov/marc/bibliographic/ecbdldrd.html are valid but Lint tells me they are wrong. Can it be that only the most common subfields have been entered into MARC::Lint? Well, anyways, i thank You all, and be sure to see me here again when i have run into trouble. -- Christoffer Landtman Oy Realnode Ab Partner, Sales +358 (0)41 510 1073 [EMAIL PROTECTED] www.realnode.fi
