I am using RDF as the data model for my meta data. The meta data will contain IOPE and the other parameter, like efficiency/accuracy which are not the part of IOPE but part of metadata for a process. There is schema for the process (http://www.daml.org/services/owl-s/1.0/Process.owl) which includes the IOPE.
1) How can I define a schema for other parameter to be present in my RDF file ?
2) I am using Protege but I also can't find a way to use the Process schema or any existing schema.
