Towards a RESTful Service Ecosystem
0 likes2,205 views
The document discusses the evolution of service-oriented architecture (SOA) and its transition to a restful service ecosystem, highlighting the challenges faced with data formatting and semantic annotation. It critiques the limitations of traditional SOA methods like SOAP and emphasizes the advantages of REST for web applications. Additionally, it explores the importance of service discovery and the potential of combining crowd knowledge with computer processing.
