They should adopt this for core joomla if fabrik agrees to it.
If you have tried using drupal cck, views to get anything FINISHED, you will instantly know how good Fabrik is.
Its a combination of drupal ck, views, notifications, rules, theming all rolled into one workflow. So once you have finished one workflow from Fabrik, its deployable, DONE!
Fabrik is intuitive.
Fabrik provides an END-to-END closed loop to develop and deliver a working application.
But the best thing is, Fabrik has a fantastic supportive community. Open source software without any assistance is like looking at 1000s of lines of code all by yourself and trying to workout what the other guy was thinking when he/she wrote it.
For a tip, get the bronze membership, it is well worth it, and helps the developers make this product even better.
Enjoy Fabrik, I do.
