Metadata-Driven Design: Creating an User-Friendly Enterprise DSL

What if we could create a language that could be easily understood by the layman but yet enforce those rules that apply to our business domain?

Thinking Outside-In: How APIs Fulfill the Original Promise of Service-Oriented Architecture

The article explores how and why APIs are a lightweight and agile way of building reusable business systems. While some SOA adopters delivered these goals many efforts faced complexity and failed.
