Thirty-seven technology companies said they have begun conducting e-business transactions using RosettaNet standards. RosettaNet is an industry group that has drafted standards to help technology companies exchange information among suppliers, manufacturers and buyers. RosettaNet has developed interfaces using the XML (Extensible Markup Language) Web standard for data exchange that helps tie companies together. Companies deploying RosettaNet include Compaq Computer, Hewlett-Packard and Intel. Analysts say RosettaNet is one of the first XML standards group to have its technology up and running.
