The MultiSpeak Specification consists of:

  • UML class models and XML schemas that document the MultiSpeak data model
  • web service description language (WSDL) files that define the messages used to implement interoperable web services
  •  a specification document
  •  use case documentation
  •  a security standard
  • endpoint schemas

The following specifications are available to MultiSpeak members:
