DESCRIPTION

This is a Perl module for creating MARC records from a hash variable. MARC::Loader use MARC::Record.

Hash keys naming convention.

The names of hash keys are very important. They must begin with letter f followed by the 3-digit field name ( e.g. f099), followed, for the subfields, by their letter or digit ( e.g. f501b).

Repeatable fields are arrays of hash ( e.g., 'f700' => [{'f700f' => '1900','f700a' => 'ICHER'},{'f700f' => '1353','f700a' => 'PAULUS'}] ).

Repeatable subfields are arrays ( e.g., 'f101a' => [ 'lat','fre','spa'] ).

Controlfields are automatically detected when the hash key begin with letter f followed by 3-digit lower than 10 followed by underscore ( e.g. f005_).

Indicators must begin with the letter i followed by the 3-digit field name followed by the indicator's position (1 or 2) : e.g. "i0991".

Record's leader can be defined with the hash key 'ldr' ( e.g., 'ldr' => 1 ).

reorder fields and subfields

Fields and subfields are in lexically order. If you want reorder fields and subfields differently, you can add a reordering string (necessarily followed by ##) at the beginning of hash keys (e.g., to reorder the subfields of f995 to have $e followed by $b : 'f995' => [{'001##f995e' => 'S2','002##f995b' => 'MP')]};). If you want to reorder fields, please note that the controlfields will always be located before the other (e.g., if you define '001##f101a' => [ 'lat','fre','spa'] , the f101 will be placed after the last controlfield ).

Be careful, the reorder is made lexically, not numerically : 10 will be placed before 2, while 002 will be placed before 010.

If the script you use to build your hash requires you to precede fields AND subfields with a reordering string when you want to reorder only those sub-fields, you can force the module to reorder the fields in alphabetical order with an hash key named 'orderfields' ( e.g., 'orderfields' => 1 ).

You can also remove non-sorting characters with an hash key named 'cleannsb' ( e.g., 'cleannsb' => 1 ).

METHOD

new()

•

$record = MARC::Loader->new($foo);

This is the only method provided by the module.
