Using ARQoid for Android-based SPARQL Query Execution
I was recently asked about the SPARQL support in Sparql Droid and whether it could serve as a way for other Android applications to execute SPARQL queries against remote data sources. It could be used in this way but there is a simpler alternative I’d like to discuss here.
On the Android platform it is actually quite easy to execute SPARQL against remote SPARQL endpoints, RDF data and local models. The heavy lifting is handled by Androjena’s ARQoid, an Android-centric port of HP’s Jena ARQ engine.
Both engines (the original and the port) do a great job of simplifying the execution of SPARQL queries and consumption of the resulting data. In this post I’ll go through a simple example of using ARQoid. Note that all the code being shown here is available for download. This post is based specifically on the queryRemoteSparqlEndpoint() method in the com.monead.androjena.demo.arqoid.SparqlExamples class.
