# Metadata

The **Metadata** module defines a metadata object. An application can obtain the metadata through [bundleManager.getBundleInfoForSelf](js-apis-bundleManager.md#bundlemanagergetbundleinfoforself), with **GET_BUNDLE_INFO_WITH_METADATA** passed in for [bundleFlags](js-apis-bundleManager.md#bundleflag). This object is contained in [ApplicationInfo](js-apis-bundleManager-applicationInfo.md), [HapModuleInfo](js-apis-bundleManager-hapModuleInfo.md), [AbilityInfo](js-apis-bundleManager-abilityInfo.md), and [ExtensionAbilityInfo](js-apis-bundleManager-extensionAbilityInfo.md).

The **Metadata** module provides the configuration about the module, UIAbility, and ExtensionAbility. The value is of the array type. The configuration is valid only for the current module, UIAbility, or ExtensionAbility.
