[jira] [Updated] (JENA-707) Hyphens in tdb:location path prevent
dataset querying when using TDBFactory
[ https://issues.apache.org/jira/browse/JENA-707?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rick Moynihan updated JENA-707:
-------------------------------
Description:
When using the Jena API and TDBFactory.assembleDataset("config.ttl") if the storage location path contains a hyphen it prevents querying at least via QueryExecutionFactory.
e.g. the following Assembler config fails, causing all queries to return empty resultsets:
{quote}
@prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix ja: <http://jena.hpl.hp.com/2005/11/Assembler#> .
# add more services here ^^
[] ja:loadClass "com.hp.hpl.jena.tdb.TDB" .
tdb:DatasetTDB rdfs:subClassOf ja:RDFDataset .
tdb:GraphTDB rdfs:subClassOf ja:Model .
<#live> rdf:type tdb:DatasetTDB ;
tdb:location "quad-store/live" ; # change to suit your local installation
# Query timeout on this dataset (1s, 1000 milliseconds)
ja:context [ ja:cxtName "arq:queryTimeout" ; ja:cxtValue "10000,10000" ] ;
tdb:unionDefaultGraph true ;
.
{quote}
But changing tdb:location to "quadstore/live" works.
