XML – the language of electronic business

ETIENNE DEFALQUE, GENERAL MANAGER, ACSE, BELGIUM,
ABOUT THE BIG BANG OF THE XML UNIVERSE

Electronic business now has its own language: XML. For years the Internet has provided connectivity. However, until now, it has been used primarily for e-mail, file transfer and Web searching. Now, with XML, the Internet opens itself to electronic business, and we are witnessing nothing less than a big bang: the explosive growth of new ways of conducting business between all kinds of organizations. The limiting factor for growth, it seems, is not the technology, now the imagination and the capacity for change, are setting the limits.

POTATO CHIPS INSTEAD OF MICROCHIPS

This development is no accident, though. XML was defined by the independent World Wide Web Consortium (W3C) under the SGML standard to make up for some of HTML's obvious shortfalls. Some people consider XML a better version of HTLM with improved mark-up functionality for Web pages.

But that is not even half the story. XML brings two major breakthroughs to the Internet.

First, XML is a powerful, yet flexible, means to organize the information content –the knowledge, or "fuel "for advanced economies –and to make it maintainable and efficiently searchable. Daily practice proves how badly needed this is:

A search on the Web for the fastest chip on the market also yields, among other things, a long list of references to "potato chips ".

HTML defines how text is displayed on the screen, but it is useless when it comes to organizing and qualifying content. All this changes with XML: Information can be structured, labeled with tags and qualified with attributes. These provide meaning and validity to the text and information on the Internet. The information can be organized, maintained, processed and understood more easily.

With data formatted in XML, and a common industry vocabulary, a search for the fastest chip can easily be put in context and deliver meaningful results. The Internet is going this way, fast. Indeed, more mergers bringing together Internet and content, like the ones between America Online and Time Warner or Vodaphone and Vivendi, will come.

Second, XML is the language that will support all automated transactions between and within all types of organizations: economic actors, administrations and communities. Advanced societies made up of interacting organizations will formalize and automate all routine transactions in the form of XML messages, which will include rich, multimedia information.

The possibilities that XML is opening up for electronic business are far-reaching. XML, being a meta-language, i.e. a language for defining languages, will leverage ideas that haven ’t surfaced yet.

INDUSTRY-SPECIFIC DICTIONARIES IN XML

Two things are necessary, though, for businesses to realize the vast potential of XML. First, applications and IT infrastructures must become XML-compatible. Products are now being delivered to the market in volume. Second –and most importantly – industry and business associations need to agree on binding definitions of their XML vocabulary and messages. The same principle that is applicable in object-oriented architecture, i.e. collaborative processing with well-defined interfaces, applies here.

A lot of progress has already been made in this area. HL7 (Health Level 7), OMF (Weather Observation Markup Format) or CML (Chemical Markup Format) are good examples of industry-specific vocabulary standards under the umbrella of XML. They are specialized dictionaries for automated data exchanges. These dictionaries can be deposited at public clearing points on the Web, such as xml.org (OASIS) or BizTalk.org (Microsoft Corp.).

Wherever possible, businesses should use standard and binding interface data models. This will unleash the true potential of XML-based collaborative chains within industries.
