Custom Metadata <customMetadata>

  • Article

Overview

The <customMetadata> element contains settings that are used internally by the metabase compatibility feature of Internet Information Services (IIS) 7.

Important

The <customMetadata> section of the configuration should not be modified directly. Use the metabase APIs to set any metabase settings that are represented in this section.

In IIS 6.0, all of the IIS settings were kept in the metabase. In addition, any custom settings that were required by applications were stored in the metabase. In IIS 7, all IIS settings are now kept in ApplicationHost.config and Web.config Files. IIS 7 provides backwards-compatibility through the IIS 6 Metabase Compatibility feature, which is sometimes referred to as the Admin Base Object (ABO) mapper component. This feature listens for applications that attempt to write to the metabase, and maps all IIS 6.0 metabase settings to their IIS 7 equivalents. If an IIS 6.0 setting has no IIS 7 equivalent, the setting will be written to the <customMetadata> element.
