4. Relevant messaging concepts 4.1. Web services and their role in an eBusiness messaging framework A major design choice in ebMS 3 is the specification of the MSH and its associated processing rules using Web Services (WS) standards. The intent is to make use of other relevant Web Services specifications that fulfill certain messaging requirements, and build upon that base by adding what is necessary for a complete and coherent eBusiness messaging service. ebMS 3 brings this all together into a single, coherent framework. In order to achieve this, message security and reliability requirements are met through the use of other Web Services standards and their implementations. The message SOAP body has been freed for business payload. The ebMS header is just a SOAP extension among others. As a result, ebMS 3 is significantly more compliant than ebMS 2 with the SOAP processing model, and apt at composing Web services standards that are defined as SOAP extensions. Compliance of ebMS 3 implementations with the latest version of WS-I profiles – once approved as final material by the organization – will be addressed in the definition of conformance profiles that are adjunct to this document (see Annex G). A compatibility mapping from ebMS 2 to ebMS 3 is provided in Annex F. Compliance with Web services standards does not remove the rationale behind an Internet-based messaging middleware. Often, document-centric eBusiness and eGovernment exchanges need to clearly dissociate messaging functions from the way these messages are consumed on the back-end. Such consumption may take place according to various models. The use of SOAP message header elements that represent standard business metadata (user or company ID, business conversation, business service and action, etc.), is a key feature for supporting a decoupled binding with back-end business processes. At the same time, experience has demonstrated that the messaging layer needs to be more supportive of business transactions: messages are parts of basic choreographies that map to higher- level business exchanges between partners. To this end, ebMS 3 supports a notion of message exchange pattern (MEP) the properties of which (reliability, security, binding to underlying transport, error handling, and other quality of service aspects such as timing, etc.) are controlled in a contract-based manner by the message producer and consumer layers.
4.2. Caveats and assumptions The target audience for this document is the community of software developers who will implement the ebXML messaging service. It is assumed the user has an understanding of communications protocols, MIME, XML, SOAP, SOAP Messages with Attachments and security technologies. All examples are informative. If inconsistencies exist between the specification and the examples, the specification supersedes the examples. Implementers are strongly advised to read and understand the OASIS Collaboration Protocol Profile & Agreement specification (CPPA) and its implications prior to implementation. This document presents some alternatives regarding underlying specifications (e.g. SOAP 1.1/1.2, WSS1.0/1.1, and Web Services specifications that support the reliability function). This does not imply that a conforming implementation supports all of them, nor that it is free to support any option. The definition of conformance profiles – out of scope for this document, and to be described in an adjunct OASIS document – will complement this document by asserting which option(s) shall be supported in order to claim support for a particular conformance profile. Conformance to compatible profiles is a prerequisite to interoperability. See Annex G for more details on conformance profiles.ISO 15000-2 pdf download.
