The Web as the world's largest information system has largely settled on a solid foundation of HTTP-based connectivity, and the representation of User Interface (UI) information resources through a mix of HTML and scripting. In contrast, the similarly rapidly evolving "Web of Services" is still based on a more diverse and more quickly evolving set of approaches and technologies. This can make architectural decisions harder when it comes to choosing on how to expose information and services through an Application Programming Interface (API). This challenge becomes even more pronounced when organizations are faced with developing strategies for managing constantly growing and evolving API landscapes.
