MW: It is not an ontology of Oil, but to support the integration and
handover of large engineering artefacts that has been developed by
the Oil and Gas and Process Plant industries. The kind of inference
you are looking for is quite core to the requirements of such
an ontology. (08)

MW: I understand your difficulty because you are used to different
formalisms. I have a sub-relation that has a relationship to the two
objects that you relate. I can see by inspection, that if I join (in
relational terms) my two relations I get yours. (09)
MW: That you do not see this does no make it untrue. (010)
MW: I will happily take you (or anyone else who is interested) through
this the next time you are in London, since I guess the gap in
understanding is too wide for the written word. (011)
