HTTP::OAI::Repository(3)

NAME
HTTP::OAI::Repository - Documentation for building an OAI compliant repository using OAI-PERL

DESCRIPTION
Using the OAI-PERL library in a repository context requires the user to build the OAI responses to be sent to OAI harvesters.

SYNOPSIS 1
        use HTTP::OAI::Harvester;
        use HTTP::OAI::Metadata::OAI_DC;
        use XML::SAX::Writer;
        use XML::LibXML;

        # (all of these options _must_ be supplied to comply with the OAI protocol)
        # (protocolVersion and responseDate both have sensible defaults)
        my $r = new HTTP::OAI::Identify(
                baseURL=>'http://yourhost/cgi/oai',
                adminEmail=>'youremail@yourhost',
                repositoryName=>'agoodname',
                requestURL=>self_url()
        );

        # Include a description (an XML::LibXML Dom object)
        $r->description(new HTTP::OAI::Metadata(dom=>$dom));

        my $r = HTTP::OAI::Record->new(
                header=>HTTP::OAI::Header->new(
                        identifier=>'oai:myrepo:10',
                        datestamp=>'2004-10-01'
                        ),
                metadata=>HTTP::OAI::Metadata::OAI_DC->new(
                        dc=>{title=>['Hello, World!'],description=>['My Record']}
                        )
        );
        $r->about(HTTP::OAI::Metadata->new(dom=>$dom));

        my $writer = XML::SAX::Writer->new();
        $r->set_handler($writer);
        $r->generate;

Building an OAI compliant repository
The validation scripts included in this module provide the repository admin with a number of tools for helping with being OAI compliant, however they can not be exhaustive in themselves.

METHODS

$r = HTTP::OAI::Repository::validate_request(%paramlist)
$r = HTTP::OAI::Repository::validate_request_2_0(%paramlist)
    These functions, exported by the Repository module, validate an OAI request against the protocol requirements. Returns an HTTP::Response object, with the code set to 200 if the request is well-formed, or an error code and the message set.

    e.g:

            my $r = validate_request(%paramlist);

            print header(-status=>$r->code.' '.$r->message),
                    $r->error_as_HTML;

    Note that validate_request attempts to be as strict to the Protocol as possible.

$b = HTTP::OAI::Repository::validate_date($date)
$b = HTTP::OAI::Repository::validate_metadataPrefix($mdp)
$b = HTTP::OAI::Repository::validate_responseDate($date)
$b = HTTP::OAI::Repository::validate_setSpec($set)
    These functions, exported by the Repository module, validate the given type of OAI data. Returns true if the given value is sane, false otherwise.

EXAMPLE
See the bin/gateway.pl for an example implementation (it's actually for creating a static repository gateway, but you get the idea!).
