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 con-
       verting 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

       To install this module via Module::Build:

	       perl Build.PL
	       ./Build	       # or `perl Build`
	       ./Build test    # or `perl Build test`
	       ./Build install # or `perl Build install`

       To install this module via ExtUtils::MakeMaker:

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.

TODO

       * Implement as_marc()
       * add tests
