14、 of Changes in this Edition 225 iv Ecma International 2012 Ecma International 2012 vIntroduction This Standard defines a Web Services Description Language (WSDL) for Phase III of Computer Supported Telecommunications Applications (CSTA). This Standard is part of a Suite of Standards and Technical Re

15、ports for Phase III of CSTA. All of the Standards and Technical Reports in the Suite are based upon the practical experience of Ecma member companies and each one represents a pragmatic and widely based consensus. This 5th Edition of ECMA-348 is fully aligned with ECMA-269 9th Edition and it imports

16、 the CSTA XML schemata from ECMA-323 6th Edition. This edition introduces WS-Eventing to establish event channels and implicit associations, and recasts outbound operations into inbound operations in the Computing Function WSDL. This change is fully conformant to WS-I and supports SOAP/HTTP as a com

17、plete binding of the WSDL. This Ecma Standard has been adopted by the General Assembly of June 2012. vi Ecma International 2012WSDL Tools Acknowledgement The WSDL definition files, for the computing function, switching function and common messages, reflecting the WSDL specifications in this Standard

25、 for CSTA Phase III 1 Scope Web Services Description Language (WSDL) is an XML schema for describing Web services and how they can be accessed by Web based applications. WSDL facilitates the creation and deployment of web based applications. For example, by using WSDL with many industry Web services

26、 development environments, a web services developer can access features provided by an implementation without knowing details of the network or underlying transport protocols. This Standard specifies two WSDL documents: Computing Function WSDL and Switching Function WSDL, for ECMA-269, Services for

27、Computer Supported Telecommunications Applications (CSTA) Phase III. All CSTA features (e.g., services and events) specified in ECMA-269 are specified in this Standard. This Standard specifies pairs of port types, one from the Computing Function WSDL and one from the Switching Function WSDL, for all

28、 the profiles specified in ECMA-269. A full WSDL document contains both abstract definitions (WSDL messages and port type elements) and concrete protocol specific definitions (WSDL bindings, ports, and service elements). This CSTA WSDL Standard specifies only the abstract definitions of a WSDL docum

29、ent. The concrete and protocol specific definitions are implementation specific and are outside the scope of this Standard. Annex B illustrates an example SOAP over HTTP binding. WSDL is defined in XML and XML Schemata. This Standard builds upon the XML data types and imports all message formats spe

30、cified in ECMA-323. Annex A specifies mechanisms to establish event channels based on WS-Eventing. The event channels allow the Switching Function and Computing Function to be both a Service Requester and a Service Provider. 2 Conformance In addition to the conformance requirements specified in Clau

31、se 2 of ECMA-269 and Clause 2 of ECMA-323, a conformant implementation supports at least one pair of the port types defined in this Standard. Each port type pair in this Standard corresponds to a profile specified in 2.3.1 of ECMA-269. To support one pair of these port types, an implementation must

32、support all the WSDL operations specified in the port type pair. A conformant implementation supports an operation by adhering to the corresponding service definition in ECMA-269 and by using the message formats and data types as specified in ECMA-323. A conformant implementation also supports the e

33、vent channel establishment specified in Annex A. 3 Normative references The following referenced documents are indispensable for the application of this document.

38、vices Eventing (WS-Eventing) W3C Recommendation 13 December 2011 4 Definitions CSTA-specific terminology is defined in ECMA TR/72. 5 Web Services Overview A Web service is the name for a service that is accessed by applications over the Internet. Conceptually this corresponds to a CSTA application (

39、client) invoking services provided by a CSTA implementation (server) in a distributed environment. Web services are more formally defined as: “encapsulated, loosely coupled contracted functions offered via standard protocols” where: Encapsulated means the implementation of the function is never seen

40、 from the outside Loosely coupled means changing the implementation of one function does not require a change of the invoking function and Contracted means there are publicly available descriptions of the functions behaviour, how to bind to the function as well as its input and output parameters. Th

41、e goal of Web services is a seamless integration of services across the different technologies (networks, software, hardware, etc.) available on the Internet. Web services require: 1. A standard way to represent data 2. A common, extensible message format 3. A common, extensible service description

42、language Ecma International 2012 34. A common way to discover service providers The first two requirements, a standard way to represent data and a common extensible message format, have already been achieved with ECMA-323. The ECMA-323 Standard includes extensible XML schemas for all of the categori

43、es of services defined in ECMA-269. NOTE This Standard satisfies the third requirement, a common, extensible service description language, by providing WSDL definitions for CSTA. UDDI (Universal Discovery, Description, and Integration Registry) and other procedures to satisfy the forth requirement a

44、re outside the scope of this Standard. There are three components involved with Web services: Service Requester provides the following major functions: 1) optionally queries a Service Broker for where to find a suitable Service Provider and 2) binds and interacts with a Service Provider. Service Pro

45、vider provides the following major functions: 1) publishes its services (e.g. WSDL document) and 2) interacts with a Service Requester. Service Broker acts as a look up service between a Service Provider and a Service Requester. A Service Broker is an optional component of a Web service. For the pur

46、poses of this Standard: A CSTA Service Requester is a Service Requester. A CSTA Service Provider is a Service Provider. A Service Broker is outside the scope of this Standard. A WS-SF is a Switching Function that acts as a CSTA Service Requester and Provider. A WS-CF is a Computing Function that act

47、s as a CSTA Service Requester and Provider. 4 Ecma International 20126 WSDL Overview WSDL enables applications to communicate with each other in an automated way. A WSDL document describes Web services both in an abstract (network independent) and concrete (with network protocol bindings, e.g. SOAP)

48、 way. A WSDL document consists of sets of definitions. There are six major elements in a WSDL document: types provides the data type definitions used to describe the messages exchanged message defines the messages contents operation defines how input and output messages are associated with a logical

49、 operation portType groups a set of operations together binding specifies concrete protocol and data format specifications for the operations and messages for a particular portType port specifies an address for a binding service used to group a set of related ports For interoperability, this Standard disallows WSDL 1.1 Notification and Solicit-response operations. Instead, this Standard uses a Switching Function WSDL to represent the Switching Function Services defined in ECMA-269
