I am getting an exception when executing the following a valid construct query on Fuseki via jena. Any idea about this problem ?
The query: ============== PREFIX dcat: <http://www.w3.org/ns/dcat#> PREFIX data: <http://opensensingcity.emse.fr/LDPDesign/data/> PREFIX skos: <http://www.w3.org/2004/02/skos/core#> PREFIX :
