Web Services Changes

The W3C and OASIS have a number of new standards for web services. The one of particular interest to PowerBuilder developers will be XOP (XML-binary Optimized Packaging), a standard means of transmitting binary data via XML. The others MTOM (Message Transformation Optimization Mechanism) and RRSHB (Resource Representation SOAP Header Block) are more under-the-covers implementations to improve performance. Unfortunately, the other key headache for web services developers is security, and those bodies are only starting to develop a common consensus on a new standard in that area.
