Long-lived DDD with "Closure of Operations"

Eric Evans' Big Blue Book has a chapter titled "closure of operations", largely ignored by the community and subsequent works on DDD. This is tragic, as closure of operations is one of the most powerful techniques for domain modeling. A concept imported from functional programming, it makes for flexible and long-lived domain models with the help of combinators - operations that build big domain objects from smaller ones recursively. This is refreshing alternative to the rigid hierarchical taxonomies that often result from naive application of DDD modeling techniques "close to the domain", and which require continual adjustments and extensions. The talk shows what "closure" is and how you can harness it in your project.

"Closure of operations" applies abstraction over rigid models. It avoids common problems of overabstraction through a systematic process and the use of simple mathematical principles. The talk will also cover these.
