Hello,
I am trying to add the following attribute designator in
$FEDORA_HOME/pdp/conf/config-attribute-finder.xml
<attribute designator="resource"
name="http://kemibrug.dk/k2/rdf#notesPids";>
<config name="queryLang" value="sparql"/>
<config name="value" value="notesPids"/>
<config name="query" value="SELECT ?pid WHERE
{?pid <dc:identifier> ?ident FILTER (REGEX(STR(?ident),
"note"))}"/>
</attribute>
For some reason it makes fedora throw exceptions when trying to access
objects in the database:
ERROR 2011-07-13 14:02:00.657 [http-8080-1] (DirectPDPClient) Error
evaluating request.

Did I do something wrong with the attribute designator? The sparql
query on its own works as intended. Did I miss something?
