NAME¶
MARC::Crosswalk::DublinCore - Convert data between MARC and Dublin Core
SYNOPSIS¶
my $crosswalk = MARC::Crosswalk::DublinCore->new;
# Convert a MARC record to Dublin Core (simple)
my $marc = MARC::Record->new_from_usmarc( $blob );
my $dc = $crosswalk->as_dublincore( $marc );
# Convert simple DC to MARC
$marc = $crosswalk->as_marc( $dc );
# Convert MARC to qualified DC instead
$crosswalk->qualified( 1 );
$dc = $crosswalk->as_dublincore( $marc );
DESCRIPTION¶
This module provides an implentation of the LOC's spec on how to convert
metadata between MARC and Dublin Core format. The spec for converting MARC to
Dublin Core is available at:
http://www.loc.gov/marc/marc2dc.html, and from DC
to MARC:
http://www.loc.gov/marc/dccross.html.
NB: The conversion cannot be done in a round-trip manner. i.e. Doing a
conversion from MARC to DC, then trying to go back to MARC will not yield the
original record.
INSTALLATION¶

METHODS¶
new( %options )¶
Creates a new crosswalk object. You can pass the "qualified" option
(true/false) as well.
# DC Simple
$crosswalk = MARC::Crosswalk::DublinCore->new;
# DC Qualified
$crosswalk = MARC::Crosswalk::DublinCore->new( qualified => 1 );
qualified( $qualified )¶
Allows you to specify if qualified Dublin Core should be used in the input or
output. Defaults to false (DC simple).
# DC Simple
$crosswalk->qualified( 0 );
# DC Qualified
$crosswalk->qualified( 1 );
as_dublincore( $marc )¶
convert a MARC::Record to a DublinCore::Record.
as_marc( $dublincore )¶
convert a DublinCore::Record to a MARC::Record. NB: Not yet implemented.

- •
- Implement as_marc()
