Microsoft has announced preliminary versions of two new software development specifications that company officials described as integral to the Internet-based .Net Web services strategy Microsoft unveiled last month.
The specifications are based on Microsoft's Simple Object Access Protocol (SOAP), which uses XML and HTTP technology to provide a common format for routing messages between different applications virus (See Microsoft's Web site for preliminary version.) The protocol ferries remote procedure calls from systems past Web site firewalls so they can exchange messages with other applications. (See Maggie Biggs' column, page 24.)SOAP was submitted to the World Wide Web Consortium (W3C) as a proposed interoperability standard earlier this year, and Microsoft officials said the new SOAP Contract Language and SOAP Discovery specifications eventually will be added to the standards proposal.
