Introduce
an “Attribute” concept to wsdl:interface
|
|
|
|
– |
Similar
to attribute in CORBA IDL
|
|
|
• |
Core
idea:
|
|
|
– |
Elements
of publicly available state are
modeled using XML
|
|
Schema
element
|
|
|
– |
State
of a Web service instance is modeled “logically” as an
|
|
|
XML
instance document
|
|
|
– |
Define
operations: get, set, query, [subscribe]
|
|
|
|
– |
Elements
of state are modeled with the interface definition as
|
|
attributes
|
|
|
|
– |
Use
attributes to convey state and meta-data of the service
|
|
|
|
– |
Client
proxy generators can still generate type-specific
|
|
|
getters/setters
(if they want)
