The ResourceIndex manages relationships between Fedora objects. It is very powerful, but the query syntax can be tricky.

The ResourceIndex's search system provides an interface that will translate queries from iTQL into URL form: RIsearch on Ryan's machine.

Sample RIsearch queries

Select objects, modification dates, and titles. Start with the 50th Fedora object, and get the next 25 objects:

select     $object $modified $title $type
from       <#ri>
where      $object <rdf:type> $type
and        $object <rdf:type> <fedora-model:FedoraObject>
and        $object <fedora-view:lastModifiedDate> $modified
and        $object <dc:title> $title
order by   $title $object
limit      25
offset     50 

Count all objects that are members of the collection object iu-dlp:2601:

select count(
  select  $object
  from    <#ri>
  where   $object 
from <#ri>
where $a $b $c
