FWIW, using a RESTful approach to composition seems to simplify things
greatly.  As each resource is a potential data source (via its state),
this enables composition to be described with containment relations.
For example, a description of the pipe "A | B" might be;

<Container rdf:about="B">
    <Container rdf:about="A"/>

That doesn't say who does the binding, i.e. whether B invoked GET on A,
or A invoked POST on B, or even if C invoked GET on A and POST on B ...
but the flow (aka route) is the same in all those cases.
