HTTP::OAI::MetadataFormat - Encapsulates OAI metadataFormat XML data

$mdf = new HTTP::OAI::MetadataFormat

This constructor method returns a new HTTP::OAI::MetadataFormat object.

$mdp = $mdf->metadataPrefix([$mdp])

$schema = $mdf->schema([$schema])

$ns = $mdf->metadataNamespace([$ns])

These methods respectively return and optionally set the metadataPrefix, schema and, metadataNamespace, for the metadataFormat record.

metadataNamespace is optional in OAI 1.x and therefore may be undef when harvesting pre OAI 2 repositories.
