2. Common Terminology Services 2 (CTS2)
Object Management Group (OMG) Standard
Focus is access, query, update and distribution of “Terminological Resources”
Standard contains:
Formal Information Model in UML
Formal Computational Model in UML
Set of XML Schemas
WADL (REST) and WSDL (SOAP) specifications

3. CTS2 An application program interface (API) specification:
It defines the semantics, syntax and valid interactions that can occur
It is a “blueprint” for software
If everyone follows the blueprint (and the blueprint is sufficiently precise) then CTS2 clients and services can interoperate

4. CTS2 Standard as a Blueprint
CTS2 Clients
An analogy might be a blueprint for an engine - a detailed specification of the various parts that go into engine assembly as well as the dimensions, requirements, etc. that would allow the engine to be used in a motor vehicle. This blueprint would allow engine manufacturers (terminology service providers) to assemble some or all of the components of the engine in a way that would allow them to be assembled into a variety of working models. At the same time, vehicle manufacturers (client software developers) could configure their components in a way that would allow engines from different manufacturers to be used in the same vehicle.

XML Schema defines required and optional components of a resource
WADL or WSDL defines how resource is accessed
REST PSM defines how to access using HTTP (Browser) GET / PUT / POST / REMOVE
SOAP PSM defines web services addess
