Hello, Is there a convenient way to import RDF/OWL data into R? I'm interested in importing BioPAX/SBPAX data into R to make them available for a wider audience. One exciting application would be to use pathway data to explain differential microarray measurements by identifying upstream nodes that are likely involved in causing the differences. This could also be used to validate pathways or to estimate concentrations or kinetic parameters. If no convenient method to import RDF/OWL exists, I would be happy to take the lead in creating a light-weight R package based on rjava and OpenRDF Sesame Rio that could query RDF/OWL data and turn the results into data frames. Thanks!
