We closed with several more talks on the technical details behind the workflow and the scripting infrastructure. The second to last talk by Neil Winstanley should probably have been right up front. We finally got some more details of the reasons behind the choice of Groovy as the workflow scripting language, some explaination of how to hook these scripts into the workflow, and what and when you need to do that.
After hearing this talk I was somewhat happier about the capabilites of the workflow engine. However, I'm still very unsure as to whether the interface being presented should be represented as the "user" level. It seems too low level to be offered directly to an average user.
