OAI


A beta version of a Perl Open Archives Initiative-Protocol for Metadata Harvesting library has been uploaded to CPAN as Net::OAI::Harvester.
Net::OAI::Harvester is a Perl extension for easily querying OAI-PMH repositories. OAI-PMH is the Open Archives Initiative Protocol for Metadata Harvesting. OAI-PMH allows data repositories to share metadata about their digital assets. Net::OAI::Harvester is a OAI-PMH client, so it does for OAI-PMH what LWP::UserAgent does for HTTP.

The guiding principle behind OAI-PMH is to allow metadata about online resources to be shared by data providers, so that the metadata can be harvested by interested parties. The protocol is essentially XML over HTTP (much like XMLRPC or SOAP). Net::OAI::Harvester does XML parsing for you (using XML::SAX internally), but you can get at the raw XML if you want to do your own XML processing, and you can drop in your own XML::SAX handler if you would like to do your own parsing of metadata elements.
