This is great. I'm happy to see more evolution in the service definition space, especially in using custom DSL's. The low signal-to-noise ratio and boilerplate in OpenAPI and RAML is a killer IMO. We're building something similar with Taxi (https://docs.taxilang.org https://docs.taxilang.org), which provides a rich way to describe services and data. Similar to Smithy's CityId example, we provide the ability to semantically describe attributes. Our product - Vyne (https://vyne.co https://vyne.co) can then use these Id's to automatically chain and orchestrate any services together, without having to write integration code.
