The Oracle Tuxedo Service Metadata Repository was developed to facilitate saving and retrieving Oracle Tuxedo service metadata. Oracle Tuxedo service metadata is a collection of Oracle Tuxedo service attributes that are especially useful in describing the request/response details of an Oracle Tuxedo service. The SALT gateway server (GWWS), relies on the Oracle Tuxedo Service Metadata Repository for conversions between the Oracle Tuxedo request/response format (buffer types) and standard SOAP message format.

When exposing Oracle Tuxedo services as Web services using SALT, you must define and load your Oracle Tuxedo service metadata in the Oracle Tuxedo Service Metadata Repository. SALT can then define the corresponding SOAP message format from the Oracle Tuxedo service metadata.

When invoking external Web services from an Oracle Tuxedo application, SALT provides a WSDL file converter, wsdlcvt. This command utility helps you to define Oracle Tuxedo service metadata from each Web service operation. The converted services are called SALT proxy services and can be invoked as normal Oracle Tuxedo services. SALT proxy services also need to be loaded in the Oracle Tuxedo Service Metadata Repository.
