+Convert MARC or MARCXML to Dublin Core metadata (XSLT Transformation),
+optionally can get an XML directly from database (biblioitems.marcxml)
+without item information. This method take into consideration the syspref
+'marcflavour' (UNIMARC, MARC21 and NORMARC).
+Return an XML file with the format defined in C<$format>
C<$marc> - an ISO-2709 scalar or MARC::Record object
-C<$qualified> - specify whether qualified Dublin Core should be used in the input or output [0]
+C<$xml> - a MARCXML file
+
+C<$biblionumber> - obtain the record directly from database (biblioitems.marcxml)
+
+C<$format> - accept three type of DC formats (oaidc, srwdc, and rdfdc )
