Eric Evans, author of the seminal book Domain Driven Design has recently given a presentation on what he has learned in the years since writing the book.

An interesting presentation worth checking out.

It was particularly nice to see time spent on the Domain Event building block and the bitter tasting Big Ball Of Mud architecture!

Greg Young has a couple of videos on InfoQ regarding his approach to domain events:

• Unshackle Your Domain
• Discussion on State Transitions
