# About Framework Settings

Many settings related to Discovery Framework can be adjusted from the Framework Settings section of the Control Panel.

Configurable settings include the following:

- df.cordaImageAuthEnabled: Controls whether Corda chart image URLs are secured.
  Note: The Corda image authorization feature is in Beta for this release and is not supported.
- df.cordaServerExternalUrl and df.cordaServerInternalUrl: The externally and internally accessible URLs of the Corda Server, which is used by the Chart component.
- df.cordaServerRedirectorUrl: The URL of the Corda Redirector, which can be used by the Chart component.
- df.dataSourceDirectory: The directory on disk from which to load data source definition files.
- df.deepLinkPortletName: The name of the deep link component.
- df.defaultDataSource: The name of the data source to use as the default.
- df.defaultExporter: The default exporter class.
- df.exportPortletName: The default name of the export portlet.
- df.healthCheckTimeout: The time (in milliseconds) for query timeout when checking data source availability on initialization.
- df.maxExportAnalyticsRecords:The maximum allowable number of Analytics records that can be exported.
- df.maxExportBaseErrors: The maximum allowable number of non-Analytics records that can be exported.
- df.mdexStateManager: The fully-qualified class name to use for the MDEX State Manager.
- df.mdexSecurityManager: The fully-qualified class name to use for the MDEX Security Manager.

The default values of these settings are created automatically upon first use. You cannot add or delete settings from the Control Panel—you can only edit them. Settings only appear after the feature(s) that use them have been executed at least once. For example, if you have never used the Chart component, the Corda Server URL settings will not appear.
