Si Chen just wrote about releasing opentaps 1.0.0, very timely just before the MySQL Conference although his suite can work with other databases too. Si spoke about opentaps at the MySQL Conference a few years ago, which is how I first met him. And he’s still at it, good for him – so it’s an active and progressing product/project. Excellent.
The opentaps project page is here: http://sourceforge.net/projects/opentaps/
Don’t know if it does (for instance) any business foo relevant for Australia yet, but asking won’t hurt, and it’s open source anyway so adding it is possible also. The joys of Open Source!
