Description: AS4 (Applicability Statement 4) is an open standard for the secure and payload-agnostic exchange of Business-to-business documents using Web services. Secure document exchange is governed by aspects of WS-Security, including XML Encryption and XML Digital Signatures. Payload agnosticism refers to the document type (e.g. purchase order, invoice, etc.) not being tied to any defined SOAP action or operation. Additional information: AS4 is a Conformance Profile of the OASIS ebMS 3.0 specification. The emergence of the OASIS ebMS 3.0 Standard [ebMS3CORE] represents a leap forward in Web Services B2B messaging services by meeting the challenge of composing many Web Services standards into a single comprehensive specification for defining the secure and reliable exchange of documents using Web Services. The ebMS 3.0 standard composes fundamental Web Services standards SOAP 1.1 [SOAP11], SOAP 1.2 [SOAP12], SOAP with Attachments [SOAPATTACH], WS-Security 1.0 [WSS10], WS-Security 1.1 [WSS11], WS-Addressing [WSADDRCORE], and reliable messaging (WS-Reliability 1.1 [WSR11] or WS-ReliableMessaging - currently at version 1.2 [WSRM12]) together with guidance for the packaging of messages and receipts along with definitions of messaging choreographies for orchestrating document exchanges. Like AS2, ebMS 3.0 brings together many existing standards that govern the packaging, security, and transport of electronic data under the umbrella of a single specification document. While ebMS 3.0 represents a leap forward in reducing the complexity of Web Services B2B messaging, the specification still contains numerous options and comprehensive alternatives for addressing a variety of scenarios for exchanging data over a Web Services platform..
