Integration languages make B2B communication more effective

... Granted, it's early going, according to experts, and adopting these kinds of communications protocols is anything but a quick-and-dirty kind of project. It can take years for systems to be built and for customers and partners to be brought fully into the loop.
But that's not stopping the Centers for Disease Control and Prevention (CDC) in Atlanta. The federal watchdog organization over flu, hepatitis and other health threats has based the messaging portion of its new Public Health Information Network (PHIN) on ebXML. The protocol will act as the standard means for exchanging messages among all 50 states and the CDC. Other users -- including clinical facilities and medical laboratories around the country -- will be brought in as well, said Barry Rhodes, associate director for public health systems development.
At this point, PHIN has been implemented in about 15 state health departments, with the rest to be rolled out over the next three years, Rhodes said. PHIN, based on a bevy of computing and other standards, is about the secure and reliable exchange of information. It's envisioned to be a unifying framework built on top of existing standards whenever possible; for instance, Secure Sockets Layer and some Java technologies are included in the system as well.
For its part, ebXML is "the envelope into which we put messages," Rhodes explained. "Some are XML messages and some are not."
The CDC chose ebXML as the underlying message transport because it liked its approach. "The developers of ebXML looked at the business need of interactions between business partners, of how that could happen." Rhodes said. "We needed that business process modeling perspective that ebXML provides. [In comparison,] Web services tools take a bottoms-up approach -- that approach is more of a solution to a technical issue, of how to distribute functionality across servers and the Internet."
So far, ebXML at the CDC has been a "success story," because it has allowed much greater interoperability than what previously occurred among the states, Rhodes said. "Our ROI is about communication and getting more information to and from the CDC."
Rhodes was not able to share specific data, but he talked about one application -- in operation for years -- that gathers information about notifiable public health threats, including E. coli bacteria and the chickenpox.
"We look at the data and analyze it for things like latency and the amount of data received -- and we have compared those to what was happening pre-PHIN," Rhodes explained. "We've seen a demonstrable increase in the amount of data and a decrease in information latency."
The biggest threat to ebXML adoption, he said, is that it's early enough in the technology's lifecycle that it's not yet a sure bet that all the major computing vendors will support it. "It's one thing to put forth a standard," he said, "but if Microsoft and IBM choose not to implement it, that makes it very difficult. Predicting the future is a hard thing." ...
