COODBMS release 0.18 now fully supports time travel. This OODBMS is built on Copy-On-Write technology and gives you the ability to freely navigate in time, viewing state and transversing links for any past time.
The project builds on Rolonics Theory, with Rolons as an alternative to JavaBeans. The next phase of development will focus on a universal (application independent) GUI written in Python--the server is Java.
Come join the fun. There is plenty to do and learn. We are reinventing software in an effort to solve many of the software industry's problems. Software developed with Rolonics is fluid, highly configurable, and requires significantly less application-specific code than any other approach.
