Manage Metadata Extensions

Metadata extensions allow additional information to be provided for metadata. Metadata extensions are defined within a Data Privacy project and apply to specific metadata. An Extensions tab at the bottom of the selected project's view is used to access the Manage Metadata Extensions view listing all of the extensions currently defined in the project. From here, extensions can be added, edited, and deleted.

When adding an extension, metadata is located using the Host Explorer-like Dataset Selection dialog box. Once the metadata has been selected, the metadata extension will be created and stored in the repository associated with the selected metadata.

The only extension currently available is a Redefines XREF for handling of COBOL REDEFINES. REDEFINES provides a way to have multiple definitions for the same positions of a record; by default Data Privacy will only use the first definition to process the data. If anything other than the first definition is to be used, a metadata extension for a Redefines XREF must be defined. Two primary uses for the Redefines XREF are to select a REDEFINES as the default definition and to select REDEFINES definitions based on testing a condition. To apply rules based on the fields within one of the REDEFINES rather than the base definition, the Redefines XREF metadata extension is used to set the base definition to IGNORE and the preferred REDEFINES to DEFAULT. To apply rules based on the fields within multiple REDEFINES that vary from record to record, a condition to test for must be specified for each REDEFINES that is to be active.
