Interoperability
*Transport-level interoperability is assumed
*At organizational level
nGuarantee messages from A to B can be executed by B (semantic level)
nInformation must have common meaning across services
WS provides the objects, not the ORB. We don’t have an underlying semantic that allows for the components to interact.

Example: if we have a non-repudiation service, everyone who uses it must have the same definition of “purchase”. 30-days vs. immediate.
