Equipment 12 preferably is used in the equipment in the electronic installation manufacturing, and such as the placement machine that is used for board production, but it also may be any electronic production equipment. As shown in Figure 1, Web service 10 is via usually using interfaces by the web service interface of 16 indications with common subscribers by 14 indications or user enterprise. The example that user enterprise uses comprises production line monitoring and production line control 18, customer relationship and management 20 and supply chain management 22. Can be arranged in the factory that comprises this equipment 12 or provide these enterprises to use 14 away from the computer of this factory. Web service interface 16 is extend markup language (XML), HTTP (HTTP) or Simple Object Access Protocol (SOAP) interface preferably.

Exploitation based on service is limited following five requirements:

A. the standard mode that represents data

B. general, extendible message format

C. general, extendible service description language (sdl)

D. find the mode of the service on the particular Web website that is positioned at

E. lookup service supplier's mode

XML is the suitable selection of the standard mode of expression data. Most standards relevant with Web service are used for data representation with XML, and utilize the XML pattern to come the data of description type. SOAP has defined the lightweight protocol that is used for information exchange. The part of SOAP standard has defined one group of rule that represents data about how with XML. The other parts of SOAP standard defined a kind of extendible message format, with the soap message form represent remote procedure call convention and with the binding of http protocol.

There is a kind of standard mode to prove that Web service 10 receives and produces what message, namely proves the Web service contract. WSDL (WSDL) is a kind of contract language of XML-based, and it is be used to making developer and developer's instrument create and explain the standard mechanism of contract. Service describing with XML-based is described Web service. This service describing has covered and necessary all details of service interaction, comprises message format, host-host protocol and position.
