cXML

cXML (commerce eXtensible Markup Language) is a <a href="/facts/Protocol_(computing)/5uady7cB">protocol</a>, created by <a href="/facts/Ariba/5pe087ng">Ariba</a> in 1999, intended for communication of business documents between <a href="/facts/Procurement/y35C00fn">procurement</a> applications, <a href="/facts/E-commerce/7vxeea0Y">e-commerce</a> hubs and suppliers. cXML is based on <a href="/facts/XML/clNgUfWk">XML</a> and provides formal <a href="/facts/XML_schema/uWam66Rj">XML schemas</a> for standard business transactions, allowing programs to modify and validate documents without prior knowledge of their form.
The protocol does not include the full breadth of interactions some parties may wish to communicate. However, it can be expanded through the use of extrinsic elements and newly defined domains for various identifiers. This expansion is the limit of point-to-point configurations necessary for communication.
The current protocol includes documents for setup (company details and transaction profiles), catalogue content, application integration (including the widely used PunchOut feature), original, change and delete purchase orders and responses to all of these requests, order confirmation and ship notice documents (cXML analogues of <a href="/facts/Electronic_Data_Interchange/ydnn0fTW">EDI</a> 855 and 856 transactions) and new invoice documents.
PunchOut is a protocol for interactive sessions managed across the Internet, a communication from one application to another, achieved through a dialog of real-time, synchronous cXML messages, which support user interaction at a remote site. This protocol is most commonly used today in the form of Procurement PunchOut, which specifically supports interactions between a procurement application and a supplier's eCommerce web site and possibly includes an intermediary for <a href="/facts/Authentication/64y4S69b">authentication</a> and version matching. The buyer leaves or "punches out" of their company's system and goes to the supplier's web-based catalog to locate and add items to their shopping cart, while their application transparently maintains connection with the web site and gathers pertinent information. A vendor catalog, enhanced for this process, is known as a punchout catalog. PunchOut enables communication between the software and the web site so that relevant information about the transaction is delivered to the appropriate channels.
Since <a href="/facts/SAP_Ariba/5pe087ng">SAP's acquisition of Ariba</a> in 2012, this protocol is owned by <a href="/facts/SAP/pVwH8lks">SAP</a>.
