The draft specification is for version 1.0 of SOAP, a method for accessing objects over the Web. Soap employs XML to let developers write apps that call objects built with Microsoft's DCOM, as well as non-Microsoft components that use Java and Corba. Microsoft hopes interoperability between its systems and computers running Unix will spur sales of Windows 2000.

Meanwhile, Microsoft and New Era of Networks (Neon)announced a strategic relationship to create and jointly market XML-based e-commerce products. Under the relationship, Neon will support Microsoft's integration and development platform, Windows DNA 2000, as well as its Babylon Integration Server and its XML-based BizTalk Server. Neon also endorsed Microsoft's BizTalk e-commerce framework and said it would join Microsoft's BizTalk steering committee, which is working on XML technology and standards.

Neon also unveiled Neon e-Biz 2000, an e-commerce integration server that supports Windows DNA 2000. The product, expected to be available next month, will provide a platform on which small to midsize companies can implement XML-based e-commerce systems. Pricing for Neon e-Biz 2000 will range from $20,000 to $70,000, based on configuration, with the average selling price expected to be around $50,000, according to the company.
