Living Architecture Documentation with xMolecules

Good architecture contains patterns. But which pattern does a given class follow? To express this directly in the code is the task of xMolecules. xMolecules is a framework-agnostic library that allows for the following:

- Annotate common architectural concepts (like layers or DDD building blocks) directly in source code. This makes it easier for human readers to understand which pattern a piece of code follows.
- Verify that rules regarding the implementation of these patterns are followed, e.g. with JQAssistant, ArchUnit(.NET), PHPStan.
- Derive the necessary technical integration and appropriate documentation. So, code generators can use the info to reduce boilerplate code.

For different programming languages (so far Java, .net, and PHP) the possibility is given to annotate code accordingly. In this talk this brand new library will be presented by one of its creators.
