distribution of “Terminological Resources”
 Standard contains:

Formal Information Model in UML

Set of XML Schemas
WADL (REST) and WSDL (SOAP) specifications
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

Using CTS2
 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
CTS2 Implementations
