Subject: Attributes
For is an improved definition and a "why" section for attributes: What? Attribute support represents a schema to describe queryable information provided by a Web service and portType operations to access and set this information. Attributes should be introspect-able at design time and runtime. Attribute is synonymous with property. For manageability, a property is a name, type, value triple that is part of the advertised manageability interface for a resource. An attribute can be used to represent configuration values, metrics, identifiers, etc. Why? Many manageability capabilities of a manageable resource take the form of information about the resource that the manager is able to query and set. While these can be accessed through individual and special WSDL operations, in management scenarios it is often required to access this information in more efficient ways (like bulk get). In order to allow these scenarios, such information should be modeled as a set of attributes (or properties) with access methods that allow access to it in ways that meet the scalability requirements of management applications.
