agroRDF is based on agroXML and has thus a very similar modular structure than the one described on the agroXML documentation page. There are comments provided directly in the turtle source files. For browsing and exploring we recommend concatenating all the files into a single model (e. g. via the command line utilities of the Redland libraries) and opening with e. g. Protégé or generating graphical representations via graphviz. We will provide sample scripts for that soon. So stay tuned.
For now, you can also use the browsing service at the iGreen data server.
