do u mean to make a Versant-alchemy? That is, something that looks more like a language and less like bunch of lowlevel getattr/getparents()-calls? i guess u'll have to make it on your own... btw There was some versant python wrapper here, ancient (1999): http://starship.python.net/crew/jmenzel/ The link maybe dead, i have the .tgz (37K) if u want it as starting point. > On Feb 9, 12:16 am, svilen <[EMAIL PROTECTED]> wrote: > > how much OO u want? > > > > There is SA, which has ORM layer over sql, so can become a > > somewhat object persistency. > > There are turboentity/activemapper, currently joining together, > > which are simple declarative layer on top of SA. > > Then here is this 'sawrapper' of mine, which is also declarative > > and wider/deeper than them, automaticaly handling all > > inheritances / decomposition and references and now able to > > convert plain python funcs (of your objects) into SA clauses.
