Christian, your thoughts, generally speaking, chime with mine. I would suggest though that the clojure community does not try to reinvent the wheel where a well-engineered one has been made elsewhere (Rich Hickey's reluctance to give clojure a yet-another-distribution/ clustering-story and instead suggest a look at existing ones is one of the many reasons I believe he has admirable and reassuring sensibilities "Given the diversity, sophistication, maturity, interoperability, robustness etc of these options, it's unlikely I'm going to fiddle around with some language-specific solution." http://groups.google.com/group/clojure/msg/4a7a866c45dc2101 - btw Rich, if you're reading this, slightly on a tangent, I do agree that I'm yet to be convinced by Erlang's distributed-at-all-time model, which you expressed reservations about based on your com/dcom experience. You may be interested to know that the SCA architecture takes these into account, and this is detailed in Jim Marino's book "Understanding SCA", which contains a discussion that echoes your view, from which I'll quote: "It may seem odd that a technology designed for building distributed applications specifies local service contracts as the default when defined in Java. This was a conscious decision on the part of the SCA authors. Echoing Jim Waldo’s seminal essay, “The Fallacies of Distributed Computing,” location transparency is a fallacy...") Christian, With regard to large data graphs, meta data, datalog/prolog and logic programming, I would suggest you take a long at RDF/OWL. It is a burgeoning field of research and my view would be that the clojure commmunity embraces it rather than attempt to reduplicate it. Is Clojure's Json-esque data model suitable for large data graphs? No, it isn't. Nor is sql or xml. That's the end of that story. But RDF/OWL is specifically designed for that, and it is very well designed. Clojure though is an ideal complement to that. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
