21、ialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical c

22、ommittees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Internat

23、ional Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.

24、 Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or a

25、ll such patent rights. ISO/IEC 29361 was prepared by the Web Services Interoperability Organization (WS-I) and was adopted, under the PAS procedure, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. INTERNATIONAL STAN

26、DARD ISO/IEC 29361:2008(E) ISO/IEC 2008 All rights reserved 1Information technology Web Services Interoperability WS-I Basic Profile Version 1.1 1 Scope and introduction 1.1 Scope This International Standard defines the WS-I Basic Profile 1.1 (hereafter, “Profile“), consisting of a set of non-propri

27、etary Web services specifications, along with clarifications, refinements, interpretations and amplifications of those specifications which promote interoperability. Section 1 introduces the Profile, and explains its relationships to other profiles. Section 2, “Profile Conformance“, explains what it

28、 means to be conformant to the Profile. Each subsequent section addresses a component of the Profile, and consists of two parts: an overview detailing the component specifications and their extensibility points, followed by subsections that address individual parts of the component specifications. N

29、ote that there is no relationship between the section numbers in this International Standard and those in the referenced specifications. 1.2 Relationships to Other Profiles This Profile is derived from the Basic Profile 1.0 by incorporating any errata to date and separating out those requirements re

30、lated to the serialization of envelopes and their representation in messages. Such requirements are now part of the Simple SOAP Binding Profile 1.0, identified with a separate conformance claim. This separation is made to facilitate composability of Basic Profile 1.1 with any profile that specifies

31、envelope serialization, including the Simple SOAP Binding Profile 1.0 and the Attachments Profile 1.0. A combined claim of conformance to both the Basic Profile 1.1 and the Simple SOAP Binding Profile 1.0 is roughly equivalent to a claim of conformance to the Basic Profile 1.0 plus published errata.

32、 This Profile, composed with the Simple SOAP Binding Profile 1.0 supercedes the Basic Profile 1.0. The Attachments Profile 1.0 adds support for SOAP with Attachments, and is intended to be used in combination with this Profile. ISO/IEC 29361:2008(E) 2 ISO/IEC 2008 All rights reserved1.3 Changes from

33、 Basic Profile Version 1.0 This specification is derived from the Basic Profile Version 1.0, and incorporates published errata against that specification. The most notable changes are: MESSAGE conformance target - Some requirements that had a MESSAGE conformance target in BP1.0 now use a new target,

34、 ENVELOPE. This facilitates alternate serialisations of the message, such as that described in the Attachments Profile. SOAP Binding - Requirements relating to the SOAP bindings serialization of the message have been moved to the Simple SOAP Binding Profile to facilitate other serializations. 1.4 Gu

35、iding Principles The Profile was developed according to a set of principles that, together, form the philosophy of the Profile, as it relates to bringing about interoperability. This section documents these guidelines. No guarantee of interoperability It is impossible to completely guarantee the int

36、eroperability of a particular service. However, the Profile does address the most common problems that implementation experience has revealed to date. Application semantics Although communication of application semantics can be facilitated by the technologies that comprise the Profile, assuring the

37、common understanding of those semantics is not addressed by it. Testability When possible, the Profile makes statements that are testable. However, such testability is not required. Preferably, testing is achieved in a non- intrusive manner (e.g., examining artifacts “on the wire“). Strength of requ

38、irements The Profile makes strong requirements (e.g., MUST, MUST NOT) wherever feasible; if there are legitimate cases where such a requirement cannot be met, conditional requirements (e.g., SHOULD, SHOULD NOT) are used. Optional and conditional requirements introduce ambiguity and mismatches betwee

39、n implementations. Restriction vs. relaxation When amplifying the requirements of referenced specifications, the Profile may restrict them, but does not relax them (e.g., change a MUST to a MAY). Multiple mechanisms If a referenced specification allows multiple mechanisms to be used interchangeably,

40、 the Profile selects those that are well-understood, widely implemented and useful. Extraneous or underspecified mechanisms and extensions introduce complexity and therefore reduce interoperability. Future compatibility When possible, the Profile aligns its requirements with in-progress revisions to

41、 the specifications it references. This aids implementers by enabling a ISO/IEC 29361:2008(E) ISO/IEC 2008 All rights reserved 3graceful transition, and assures that WS-I does not fork from these efforts. When the Profile cannot address an issue in a specification it references, this information is

42、communicated to the appropriate body to assure its consideration. Compatibility with deployed services Backwards compatibility with deployed Web services is not a goal for the Profile, but due consideration is given to it; the Profile does not introduce a change to the requirements of a referenced s

43、pecification unless doing so addresses specific interoperability issues. Focus on interoperability Although there are potentially a number of inconsistencies and design flaws in the referenced specifications, the Profile only addresses those that affect interoperability. Conformance targets Where po

44、ssible, the Profile places requirements on artifacts (e.g., WSDL descriptions, SOAP messages) rather than the producing or consuming softwares behaviors or roles. Artifacts are concrete, making them easier to verify and therefore making conformance easier to understand and less error-prone. Lower-la

45、yer interoperability The Profile speaks to interoperability at the application layer; it assumes that interoperability of lower-layer protocols (e.g., TCP, IP, Ethernet) is adequate and well-understood. Similarly, statements about application-layer substrate protocols (e.g., SSL/TLS, HTTP) are only

46、made when there is an issue affecting Web services specifically; WS-I does not attempt to assure the interoperability of these protocols as a whole. This assures that WS-Is expertise in and focus on Web services standards is used effectively. 1.5 Notational Conventions The keywords “MUST“, “MUST NOT

47、“, “REQUIRED“, “SHALL“, “SHALL NOT“, “SHOULD“, “SHOULD NOT“, “RECOMMENDED“, “MAY“, and “OPTIONAL“ in this document are to be interpreted as described in RFC2119. Normative statements of requirements in the Profile (i.e., those impacting conformance, as outlined in “Conformance Requirements“) are pre

48、sented in the following manner: RnnnnStatement text here. where “nnnn“ is replaced by a number that is unique among the requirements in the Profile , thereby forming a unique requirement identifier. Requirement identifiers can be considered to be namespace qualified, in such a way as to be compatibl

49、e with QNames from Namespaces in XML. If there is no explicit namespace prefix on a requirements identifier (e.g., “R9999“ as opposed to “bp10:R9999“), it should be interpreted as being in the namespace identified by the conformance URI of the document section it occurs in. If it is qualified, the prefix should be interpreted according to the namespace mappings in effect, as documented below.
