Accessing Publicly Available State
•We would like service requestors (for example management applications) to be able to:
–Access publicly available state data from Web services
•We would like service providers to:
–Declare which elements of their state are publicly accessible
•Modeled at the interface level
•Which elements are readable, writeable, subscribable
–Declare operations that allow get, set, query across multiple elements, and subscribe
–Declare “dynamic state data elements”
•e.g. elements of state that are available only because of a particular service life cycle value.
