For my project i've built an html/js page for show a graph with individual from my stardog database. A java server is between the html/js page and the stardog for write sparql request, execute them and then convert the result for the graph.
I use pragma describe.strategy bidirectional for my requests.
Example : DESCRIBE http://medicis.univ-rennes1.fr/ontologies/ontospm/OntoMEDIRAD.owl#Patient_f4df4492-4e04-42f2-a20f-a3208d4021cc
In some cases i have an error : org.openrdf.query.QueryEvaluationException: LongHashSet can't handle long element which equal to 0
The project and the code are here :
https://github.com/MediCIS/semanticTransaltor
The datas used for test : https://drive.google.com/file/d/10EHWVmaNmp13cCDmh_Oms6zqwxOoT2lT/view?usp=sharing
The requests used are here : https://docs.google.com/spreadsheets/d/1wuYIV8zQoYTCmX3v--XlimPsQWPo4vHi6JZZH91ckKc/edit?usp=sharing
(all of them have no errors when i use the stardog web admin page
My stardog is stil Stardog 5.3.1
Thanks you
