New developments at OASIS
New version 3.0 of ebXML Messaging, OASIS Standard, Core and Profiles  Functional improvements






“Client-only” message endpoints to better support (very) small organizations (e.g. dentists, GP offices) Intermediaries that can store messages while endpoints are off-line Large message handling Convergence with Web Services standards



Updated technical basis


Summary and conclusions (1)


Advanced messaging like ebMS is enabling technology that helps:




   

Provide better information where and when needed, leading to better health and care for every patient Deliver faster, safer and more convenient patient care Improve efficiency of healthcare services Develop new services Connect more partners, large and small Transform the healthcare system

Summary and Conclusion (2)


Standards-based messaging


    

Offers investment protection and economies of scale Leverages experience and expertise Provides vendor independence and choice Simplifies testing and error correction Supports integration and collaboration Provides natural interfaces to “decouple” systems and partners
