Jorgen Thelin writes, about the Third Age of Web Services.He brings an interesting perspective :
First Age of Web Services - Basic Web Services
• Focus was on creating the base communication and messaging layer - including SOAP, WSDL and UDDI specifications.
Second Age of Web Services - Advanced Web Services
• Focus was creating the WS-* stack for Advanced Web Services - including WS-ReliableMessaging, WS-AtomicTransaction, WS-SecureConversation and WS-Policy specs among others.
Third Age of Web Services - Applied Web Services
• Focus is now on applying the Web services stack to specific applications and vertical domains.
The most recent examples of these usages include the Identity Metasystem (based primarily on WS-Trust), WebSSO (based primarily on WS-MetadataExchange), and slightly older examples include the Devices Profile for Web Services and WS-Management.In short, it seems like the WS-* stack is now merging into the core plumbing, and attentions focused on usage of plumbing to do new and cool things with distributed systems.
