Twinkle is a simple SPARQL client. It's a fork of http://ldodds.com/projects/twinkle with a possibility of giving credentials when connecting to an endpoint with Basic Auth. The credentials might be defined in the config file as follows:
<http://192.168.1.112:3030/renku/sparql> a sources:Endpoint
; sources:username "admin"
; sources:password "admin"
; rdfs:label "Local Jena".
To run the app, the twinkle.jar needs to be downloaded as well as JRE be available. The run command is:
java -jar twinkle.jarThis project seems to be pretty old Ant project and although some libraries has been updated there's tons of work to be done.
