Welcome to this Roundtable Q&A. We posed our roundtable question to several leading authorities to gain insight from the experts in the trenches.
searchMiddleware: What do you see as the most important emerging XML standard?
Dr. Charles Goldfarb:
"XPointer. One of the biggest problems on the Web is the miserable navigation. A link has to take you to the top of a page -- even if the interesting part is near the bottom -- unless the designer put in anchor tags. XPointer lets you link anywhere in a page without the page designer having to do a thing. The standard is only supposed to be for XML, but an implementation should be able to handle HTML reasonably well. After all, they're both SGML."
"We first need to get the core communication standards such as XML Schema, SOAP, and WSDL straight, especially with respect to interoperability. This might take a couple more iterations, but we are getting there.
On top, there are very promising higher-level frameworks, such as the OASIS Business Transaction Protocol (BTP), a transaction protocol with takes the loosely coupled nature of Web Services into account. IBM has started some very interesting work with the Web Service Endpoint Language (WSEL), which deals with establishing service level agreements between Web Service providers and subscribers."
"SAML. Security Assertion Markup Language. This is the standard for passing security assertions from process to process. Using SAML one process can authenticate a user and then call another and tell the other process that this user is a certain type of trusted user-without necessarily giving the user's identity away.
For example, system one can authenticate and determine that you are a premium user and have paid your fees for the year. System one then calls system two and tells system two about your status. System two can determine whether to provide its service based on your security assertion-however system two doesn't need to know exactly who you are-just what your assertions are. SAML is needed to help complete the Web services picture just as transactions are needed."
"SOAP is without doubt the key to Web Services. Utilizing existing network infrastructures such as Http and Smtp makes way for widespread usage of Web Services across the enterprise.
We are very interested in the potential applications of Web Services with Smtp which opens very exciting new opportunities."
"E-business today is based on or has its origins in XML. XML will continue to be the way in which data is represented, services are described, and interactions are defined. As for emerging XML standards, I would say that SOAP (Simple Object Access Protocol) and ebXML (Electronic Business XML) may have the greatest impact on how applications will communicate with one another and just how successful Web services becomes."
