I'd very much like to see our efforts joined, because I'm currently developing a free Core Data implementation (http://gscoredata.nongnu.org). Around 15000 lines of code have been written so far and the last hurdle to overcome in the implementation is storage of objects. Finished parts include: - object graph management - object model - a modelling app (DataBuilder) Unfortunatelly, many parts are yet largely untested, so there's still quite a lot of work to be done, but progress is inevitable :-) -- Saso _______________________________________________ Discuss-gnustep mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnustep
