After talking with some people at the DevCon in London and after looking at Records Management source code I noticed that there's actually no good example of how to implement custom documents lifecycle. I know there's examples of rules and content modeling and even workflows but that solutions can't be really used to implement something more serious like Records Management.

What I'm wondering is how to effectively map a Java solution (I have more experience with OO and Java than Alfresco) to Alfresco. What should be defined as Java class and what should be type/aspect in content model. When to favor behaviour over rules and when to actually use workflows. In my first few projects I used workflows to implement document lifecycle, I wrote quite a lot of bussines/domain logic in workflow nodes - as actions (JS). I found out later that this is quite hard to maintain since you have some code in workflows, some in repository as scripts (Data Dictionary/Scripts) some Java, ...

Is the Records Management good example to start learning from and see some best practices in implementing full document lifecycle? Are there any other resources?

I'm strugling the most with how to implement full lifecycle in java and how to "centralize" the bussines/domain logic.
