I'm still a little confused I think. I have an object with some RELS-EXT:
<rdf:Description rdf:about="info:fedora/demo:_3e7189f7a42f4ed7be2969642e469480">
<owner
xmlns="http://www.nsdl.org/ontologies/relationships#";>demouser</owner>
<isInCategory
xmlns="http://demo/relationships#";>demo:category_skills</isInCategory>
<isInCategory
xmlns="http://demo/relationships#";>demo:category_technical_skills</isInCategory>
<isInCategory
xmlns="http://demo/relationships#";>demo:category_mindmapping</isInCategory>
</rdf:Description>
from the RI search:
select $object $modified $title $type
from <#ri>
where $object <fedora-model:hasModel> $type
and $object <fedora-view:lastModifiedDate> $modified
and $object <dc:title> $title
order by $title $object
only returns one:
info:fedora/demo:category_mindmapping
which is the last one in the RELS-EXT relationships. Curious why only one
returned. Also what would be a general query to return all objects that have:
isInCategory demo:category_mindmapping
thanks,
Alistair

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
