Hello, I created a prototype that can read RDF (using rJava and OpenRDF Sesame) and turn it into a data frame. Then I discovered that Egon Willighagen did almost the same and created RRDF (except that he used Jena instead of Sesame). RRDF does not provide a simple method to get a dataframe, but that should not be hard to add. Less work probably than turning my prototype into a deployable package.

Oliver's proposal to parse the RDF triples into a data.frame has lots to recommend it. It would be immediately useful, and yet also allow for more sophisticated uses later. With these relationships in R, annotated as BioPAX data often are, we can imagine interested parties writing S4 classes which use the data, which might provide flexible querying capabilities, and be able to transform those triples into graphs and networks, for further computation and display. >>> >>> Please let us know if we can help. >>> >>> - Paul >>> >>> >>> On Jun 15, 2012, at 12:23 PM, Oliver Ruebenacker wrote: >>> >>>> Hello Martin, >>>> >>>> I don't have code in R to test yet, but I do have extensive >>>> experience handling BioPAX in Java, so I'm assuming reading BioPAX >>>> using RJava should not be too difficult. >>>> >>>> The best target format depends on what people would like to do with >>>> the data.

It's a philosophical question if reactions should have nodes or should sit on the edges :) So far I have not used any R graph package. But I assume there are some very generic packages which are flexible enough to support both direct and bi-partite pathway structure. I used e.g. the JUNG graph API for JAVA extensively. >>>>> >>>>> I'm not sure what you mean with RDF/OWL triples. For me BioPAX is only a format to store a pathway.
