  • Computer-implemented method for generating distributed object interfaces from metadata
    Patent number: 6023579
    Abstract: A method and system for creating a distributed object interface description and a distributed object server interface module to a software system, such as a repository. In a preferred embodiment, a repository contains an object oriented information model from which an interface description and a server implementation interface module can be generated. A metadata interface allows a generator program to obtain detailed information about the information model. The generator program uses the metadata to create the interface description for the model. The generator program also generates implementation classes that will serve as the interface module between the distributed object interface and the repository.
