[Virtuoso-devel] [FCT API] datatype 'string' returns no results

[Sherman Monroe]

Hi All,

When I set the datatype of a property to a 'string' value, I get no results.

<query timeout='2000' xmlns='http://openlinksw.com/services/facets/1.0'>
> <text property='http://www.w3.org/2000/01/rdf-schema#label'>dog
> breeds</text>
> <property iri='http://www.w3.org/1999/02/22-rdf-syntax-ns#type
> '></property>
> <value datatype='uri'>http://dbpedia.org/resource/Category:Dog_breeds
> </value>
> <property-of iri='http://www.w3.org/2004/02/skos/core#subject'>
> <property iri='http://dbpedia.org/property/lifeSpan'>
> <value datatype='string'>12-14 years</value>
> </property>
> <view offset='0' limit='25' type='list'></view>
> </property-of>
> <value datatype='uri'>http://dbpedia.org/resource/Category:Dog_breeds
