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
On an XO-1 running the software 12.1.0
- Put the files "setup.sh" and "semanticxo.tar.gz" somewhere on the XO
- Login as root, set setup.sh to be executable and type "./setup.sh setup". This will install the API of SemanticXO, the triple store and two demo activities
- Reboot
