The approach below is to replace the ParameterDefinition in the current specification with the =oslc:Property= value type. It seems to provide all of the concepts needed: “required-ness”, default values, etc. Everything except the actual name of the parameter itself - and it seems that dcterms:title could be used for this value. For this proposal, a new attribute oslc_auto:parameterName is used. This will be a point for discussion.
To convert the sample below to XML, copy/paste it here: http://www.rdfabout.com/demo/validator/ and use Input Format of Turtle.
