The creation and configuration of the MetadataExtensions.cfg text file is necessary to view the Metadata tab in Phoenix RSM applications where the application reads the file (such as in Data Service Policies), and for optional extended metadata searches in applications such as Surveillance Video Manager. The Metadata tab only displays if it has been configured. The configuration process is intended for advanced users.
Metadata extensions for Phoenix RSM search applications are all covered in MetadataExtensions.cfg.
The Metadata tab appears in Surveillance Video Manager only if these applications find a MetadataExtensions.cfg file in <install-dir>\Config.
When you create, configure, and implement a MetadataExtensions.cfg, the Metadata tab appears in Data Service Policies; they contain the Query blocks listed in the DataServicesExtMd block.
