  • Mechanism for metadata for an information catalog system
    Patent number: 5721911
    Abstract: An extension of an information cataloging metadata model allows metadata users to link objects in a linear or peer-to-peer relationship (not hierarchical). Additional elements include adding a metadata functional category whoes object instances logically attach to other metadata objects in an information catalog (or information directory). Finally, the information cataloging metadata model is extended to enable metadata users to launch applications which can use values from any metadata object type as parameters to applications.
