This context is used to provide a set of exemplar DEXs and templates.
It is intended to illustrate the various artefacts of PLCS.
If data exchange scenarios are to be supported for which additional reference data is required, then new OWL ontologies should be created that import from http://www.plcs.org/ns/plcslib/data/contexts/Exemplar/refdata/Exemplar-rdl/Exemplar-rdl-en.owl. The new OWL ontologies then becomes Reference Data Library used by the DEXs.
