Hi Don: In your JTS paper you write: JTS ... providing domain-independent tools for creating domain-specific languages and component-based generators ... JTS is a set of precompiler-compiler tools for extending industrial programming languages. Both of those statements are also true for Demeter/Java. See http://www.ccs.neu.edu/research/demeter/evaluation/gte-labs/ for a commercial application. In Austin we did not talk about Demeter -> JTS transfer; I think that strategies fit perfectly into JTS. See: ftp://ftp.ccs.neu.edu/pub/people/lieber/strategies.ps Best regards, -- Karl ------- Hi Karl: Please send me a copy of your "Evolution of Object Behaviour using Context relations" paper (and anything else that you think is relevant to our conversations). thanks so much, don.
