Interesting new (asynchronous) capability with XDS.b
As some of you may have noticed already, we have recently completed moving our HealthIT content from the MSDN site https://msdn.microsoft.com/health to the new Microsoft in Health Architecture & Technology site at https://www.microsoft.com/industry/healthcare/technology/default.mspx. The old (msdn) link will become invalid sometime around February 2009. In the meantime, it will transfer you automatically to the new microsoft.com site.
Now that we are done with this work, I can resume (or startJ) my blogging activities to update you on some of the great and exciting work we are doing at Microsoft in Health these days.
On August 22nd, IHE released the Cross Enterprise Document Sharing (XDS.b) Asynchronous Web Services Exchange trial implementation supplement that you can access here.
This means that implementers can now start building support for Asynchronous Web Services Exchange in their XDS.b solutions and prepare their systems for testing at the next Connectathon event in Chicago in February 2009. Implementers will also have the option to showcase their solutions at the HIMSS Interoperability Showcase in Chicago in April 2009. Deadline to register for both events is September 30th, 2008.
Cross-Enterprise Document Sharing XDS.b is a Microsoft Health Information Network (HIN) reference implementation based on the IHE (www.ihe.net) XDS.b integration profile. XDS.b facilitates the registration, distribution and access across health enterprises of patient electronic health records. It provides a standards-based interoperable approach for managing the sharing of documents between any healthcare enterprise, ranging from a private physician office to a clinic to an acute care facility. XDS.b improves patient safety and staff efficiency by allowing timely access to patient data at the point of care. The XDS.b reference implementation is also Microsoft Connected Health Platform solution accelerator that is aligned with the architecture principles and guidance of our Connected Health Framework – Architecture and Design Blueprint.
Asynchronous Web Services Exchange is an XDS.b option that adds support for network infrastructures where:
· Transports are unreliable
· Systems are not always available
· Variable or high communication or processing latency is present
Characteristics that are mainly present in cross enterprise, regional, or national infrastructures. Asynchronous Web Services Exchange enables loosely coupled architecture, which is one of the core tenets of SOA architectures.
As part of Microsoft Health team commitment to interoperability, we released last year the XDS.b reference implementation for the Document Repository and Registry Actors to the Microsoft project hosting web site www.codeplex.com/ihe.
We will be updating the XDS.b reference implementation to include this new Asynchronous Web Services Exchange capability and will be posting a new release to the same codeplex site later this year. You will see a release timeline in the next 2 or 3 weeks.
