OAI-PMH update

a pull request has been submitted to bring this change into the core EPrints: https://github.com/eprints/eprints/pull/324

Install the package from the Bazaar http://bazaar.eprints.org/411/ 😎 - or copy:

WARNING:

If manually installing, do not copy cgi/oai2 without first copying zz_oaipmh_patch_core_EPrints_OpenArchives.pl.

Without the patch to EPrints::OpenArchives, metadata for records not in the archive will be available to harvest.

The changes to cgi/oai2 code will change the default filter for OAI-PMH records from 'in archive OR deletion':

push @$filters, {
    meta_fields => [qw( eprint_status )],
    value => "archive deletion",
    match => "EQ",
    merge => "ANY",
};

to 'has datestamp':

push @$filters, {
    meta_fields => [qw( datestamp )],
    match => "SET",
};

Any record with a datestamp, that is not in the live 'archive' dataset will be reported as 'deleted' over OAI-PMH.
