An ebXML Update - Latest News and Technology Globally ebXML technology has entered the mainstream with the Chinese government alone deploying 11,000 ebMS servers, and Europe and Asia committing to ebXML projects. Here in the US the healthcare community is moving to adopt ebXML with various initial projects underway and the US DOD EMall system is also using ebXML.  A selection of major industries including electrical utility, automotive and aerospace are in early stage adoption. To support all this ebXML is evolving rapidly and providing industry leading concepts and capabilities.  The new ebXML BPSS V2 from OASIS marks a watershed in this respect with context mechanisms, state mechanisms, support for using web services with ebXML, content transformation services and enhanced deterministic multiparty scenario modelling with forks and joins.  Similarly ebXML Registry V3 is now providing Semantic Web capabilities, and Federated Registry services. Put together the ebXML components now provide a richer and more complete foundation than ever before for robust and reliable electronic business.  This provides a service orientated architecture foundation that is globally deployable using open standards. This presentation will bring all this together and provide a comprehensive roadmap of the latest technology capabilities available through using ebXML today.

2. Quick Summary
These slides show the architecture ideas around enabling digital bags within the healthcare arena, and use of BizID mechanisms to track patient e-Services
The focus is taking the current XDS infrastructure and enhancing it with additional components to enable this
Existing open standards work in OASIS is leveraged heavily – including XACML, Registry, jCAM and EPR.
The aim is to show how to use these components synergistically together to create a feasible solution – (rather than an ultimate utopian perfect solution – 80:20 rule applies).
This discussion document is intended to lead to a formal specification to augment XDS into Phase 2.

5. Processing Details – BizID folders
One or more BizID finger prints link to the personae information – such as business card, school profile, soccer team, healthcare, financial and private information. Users can control their own activity archive to ensure approved access and also to audit access. Users also maintain their own personae and update their demographic information. A digital bag folder contains the basic information, one or more profiles relating to a business application, then supplemental content for those profiles, that may be open, or secure information – such as patient diagnosis and treatments, banking information and so on.

6. Processing Details – Blue Prints and Footprints
The blue print process is driven by the content assembly mechanism (CAM) that dynamically based on content, renders result information. It can also validate the in-bound requests, or incoming digital bag updates – to ensure they conform to the information profiles. The blueprint itself consists of use cases and associated processing templates. The OASIS jCAM engine and CAM specification fully supports this processing need today. Footprints are the information sent out and where it is sent to.

7. Processing Details – XDS Components Detail
XDS uses its process flow model and the ebXML Registry model foundation to provide secure and reliable services in support of digital bag processing. Registry systems can be standalone, or federated. Federation allows secure storage within facilities – such as a cancer treatment center, while exposing shared links to a patients digital bag for retrieval by authorized and authenticated entities.
