I try to give another view of the problem:

A service publishes its Process Ontology in which an atomic process
checkFlight,having as inputs departureLocation and arivalLocation is defined.
An agent,having planning capabilities finds this Process specification and
tries to build a planning domain, by translating the atomic processes and
their inputs to planner operators(an operator consists of an operator name
and its parameters,e.g.(checkFlight ?departureLocation ?arrivalLocation)).
When parsing the Process Ontology, using e.g. Jena, and translating the
atomic process to the operator name and its inputs to operator's parameters,
I get either
(checkFlight ?departureLocation ?arrivalLocation)
(checkFlight ?arrivalLocation ?departureLocation)

Supplementary information is needed for the agent which translates the
atomic process, such that it should generate an operator like (checkFlight
?departureLocation ?arrivalLocation) and not an operator like (checkFlight
?arrivalLocation ?departureLocation) as the service interprets the first
parameter as a departure location and the second parameter as an arrival
location. Should this kind of information be supplied in the
Process Ontology by using a RDF-Sequence?
This will change look of the process ontology by adding something like:
  <rdf:Seq rdf:about="Params">
    <rdf:_1 rdf:resource="#departureLocation"/>
    <rdf:_2 rdf:resource="#arrivalLocation"/>

Or how should this information be provided?

Thank you,
