Collection elements by <dc:description>

A QUERY Datastream is an ITQL query that overrides the Islandora’s default ITQL query.

• Default ITQL query (sites/all/modules/islandora-github/CollectionClass.inc):

$query_string = 'select $object $title $content from <#ri>
                 where ($object <dc:title> $title
                 and $object <fedora-model:hasModel> $content
                 and ($object <fedora-rels-ext:isMemberOfCollection> <info:fedora/' . $pid . '>
                 or $object <fedora-rels-ext:isMemberOf> <info:fedora/' . $pid . '>)
                 and $object <fedora-model:state> <info:fedora/fedora-system:def/model#Active>)
                 minus $content <mulgara:is> <info:fedora/fedora-system:FedoraObject-3.0>
                 order by $title';

• Add datastream “QUERY” to collection with new ITQL query:

select $object $title $content $description from <#ri>
where ($object <dc:title> $title
and $object <dc:description> $description
and $object <fedora-model:hasModel> $content
and ($object <fedora-rels-ext:isMemberOfCollection> %parent_collection%
or $object <fedora-rels-ext:isMemberOf> %parent_collection%)
and $object <fedora-model:state> <info:fedora/fedora-system:def/model#Active>)
minus $content <mulgara:is> <info:fedora/fedora-system:FedoraObject-3.0>
order by $description

• NOTE: %parent_collection% will be replaced by <info:fedora/' . $pid . '> in php code.
