NAME

SeeAlso::Identifier::PND - identifier in the German Personennamendatei (PND)

DESCRIPTION

This class handles an identifier in the German Personennamendatei (PND). The PND is a name authority file used in libraries and museums to unambiguously identify authors and other people. Because names cannot be used to identify authors (homonyms, synonyms), each person record in the PND has a unique identifier, the PND number, which is modeled with SeeAlso::Identifier::PND. A PND number consists of eight digits and a checkdigit which may also be 'X'.

This subclass of SeeAlso::Identifier overrides the constructor new and the method valid.

METHODS

new ( [ $value ] )

Create a new PND identifier.

value ( [ $value ] )

Get and/or set the value of this identifier.

valid

Check for validness.
