Perhaps we could adapt some of the ideas used within the FIPA
architecture to help achieve these objectives. Specifically,
the FIPA ACL Message Structure Specification may have some value
Basically, FIPA ACL messages carry with them meta-data
describing the language, encoding and ontology associated with
the payload. I'm not sure that the performatives or the control
of conversation aspects make sense for OOR, but the meta-data
describing the pay load might.
Just a thought.
