•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.
