Commerce XML (cXML) is a standard for the online exchange of business transaction information in common formats. It defines the structure of purchase orders, order acknowledgements, and other core e-business documents. cXML is a document type definition (DTD) based on XML tags that defines fields for a specific type of document, like a purchase order. The XML structure enables an application program to easily extract data and deliver it to another application program.
Online catalog company Ariba Technologies led the cXML effort, but more than 40 companies collaborated on cXML, including Hewlett-Packard and Microsoft. The organizations hoped a common standard would reduce the cost of doing business online. The first version of cXML (version 0.91) appeared in May 1999.Content Continues Below
