What is Commerce XML (cXML)?
Commerce XML (cXML) is a standard business transaction protocol designed for the transfer of business documents between suppliers, e-commerce hubs, and procurement applications.
The cXML protocol uses XML to provide XML schemas for common transactions and enables various programs to validate and modify documents without knowing the document form. It is used to describe company details and transaction profiles, the contents of catalogs, modified and original purchase orders (POs), deleted purchase orders, responses to all such purchase orders, and order confirmations and shipping notifications.
The first version of cXML was version 0.91, which was created in May 1999. Led by Ariba Technologies, more than 40 companies, including Hewlett-Packard and Microsoft, worked together to produce cXML. The cXML protocol is a free download along with its Document Type Definition (DTD). It may be used without restrictions, except that changes are published and the new protocol is named.
