Introduction on MileGate

We performed a feasibility study and suggested a manner for the implementation.

The suggestion contains:

functional design

sequential interactions

discovery/requesting mechanism

GUI prototype

generation of the files

reaction on modifications

HTML Generation

No client

installation

needed !

Principle

Performed work

Further development / Suggestions

Web Service

W3C definition

public interfaces and bindings are defined and described using XML

interact with the Web service in a manner prescribed by its definition, using XML based messages conveyed by Internet protocols

Basic components of Web Service Architecture

Communication

Service Description

Directory Service

Web Service - Priciple

SOAP

WSDL

optional, not used

Feasibility of a Web Service has already been proved

Functional prototype running on Linux

Embedded HTTP Server Barracuda

The new parts added to the WSDL file are:

new fault type

header & fault messages

Integration of fault into operation’s

WS-Transfer “soapAction” for operation’s

automatic binding of the headers into the SOAP messages

wsdl:service element with the Endpoint References

Web Service – Performed work

XSLT

New discover message just for MO’s

Use of relationships for operations

Adaptation of notification mechanism

Meta constraints for invocation of operations

Many other possibilities as

advertisement of new endpoints

operational status of resource

customized requests and more

..need to be analyzed carefully!
