Features/Semantic Web/Testing

On a desktop PC

This is a step by step intruction guide to test the triple store based Journal backend. It assumes that all the packages for sugar are available and the sugar-emulator is running.

• Download and install RedStore

Follow the instructions on http://www.aelius.com/njh/redstore/ to download and install RedStore on the test machine. It should also be possible to use other triple stores such as Virtuoso or OWLIM as long as a SPARQL 1.1 compliant service is accessible on the port 8080.

• Install the dependencies for SemanticXO
  • RDFLib http://code.google.com/p/rdflib/
  • SPARQLWrapper http://sparql-wrapper.sourceforge.net/

• Download and install the code from SemanticXO

Clone the repository:

 git clone git://git.sugarlabs.org/semanticxo/main.git semanticxo

Edit line 4 and 5 of datastore/bin/datastore-service to make it fit the location of the directory where you clone the code (by default ~/Code/SemanticXO) Locate the datastore-service startup script from the normal datastore

 type datastore-service

Replace that daemon with datastore/bin/datastore-service

• Start redstore in debug mode, so that you will see the queries being executed ;-)

 redstore -v

• Start the sugar emulator

 sugar-emulator

• Play around with Sugar, creating and updating entries in the Journal

• With an explorer, within the emulator or outside, go to http://localhost:8080/ to see the content of the triple store. There should be one named graph per Journal entry
