Location-to-Service Translation (LoST) Service List Boundary Extension
Abstract
Location-to-Service Translation (LoST) maps service identifiers and
location information to service contact URIs. If a LoST client wants
to discover available services for a particular location, it will
perform a <listServicesByLocation> query to the LoST server.
However, the LoST server, in its response, does not provide context
information; that is, it does not provide any additional information
about the geographical region within which the returned list of
services is considered valid. Therefore, this document defines a
Service List Boundary that returns a local context along with the
list of services returned, in order to assist the client in not
missing a change in available services when moving.
