This is certainly heading tangential to XML-DEV's charter at
this point, but..
I've recently been tackling the tuple/tree issues, but not
directly related to Linda or TupleSpaces at all. The drools project
(http://drools.org/) provides a object-oriented face (hence, graphs and
trees of objects) to a rules-engine using Forgy's tuple-based algorithm.
Coincidently, it also is semantics-agnostic. Right now it works with
Java object semantics. Next week it'll have XML semantics. I've got a
guy thinking hard about an RDF semantics module for drools.
