Metadata

IContentMetadata

The common base schema _Content, that all content types inherit, has a property _metadata of type IContentMetadata.

Content can be displayed as stand-alone instances and as part of other content inside content areas. IContentMetadata is the common signature for content metadata regardless of whether it is a stand-alone or part of another instance.

The schema IContentMetadata consists of:

Property	Type	Description
`key`	String	Unique identifier of a content instance. The `key` currently uses a UUID-based format, but this may change, and you should treat the key as an opaque string.
`locale`	String	The locale is in the format 'language code-country', like 'en-US'. For invariant cultures, the country is omitted, like 'en'. Content that is not localizable has an empty string value.
`version`	String	The `version` uses an integer-based format, but this may change, and you should treat the version as an opaque string. The version identifier is guaranteed to be unique across versions with the same key.
`url`	ContentUrl	The URL for the content item. The URL consists of several parts depending on the type of content and the application definitions. See Property Schemas-ContentUrl for information.
`types`	[String]	A list of types, where the first item is the content type and then base types.
`published`	DateTime	A datetime specified when the content instance was published. For drafts, published is null. It can also be a future datetime and is then filtered from public queries until the published time is the present time.
`status`	String	Specifies the status of the content version. See Content version status values.
`created`	DateTime	A datetime specified when the first content version in the current locale was created.
`lastModified`	DateTime	Specifies when the content version was last modified.

InstanceMetadata

For stand-alone instances, _metadata can be cast to InstanceMetadata, which inherits IContentMetadata but adds more properties. An example of a query that casts to InstanceMetadata is:

query RouteSegmentQuery {
  _Page {
    items {
      _metadata {
        displayName
        ... on InstanceMetadata {
          routeSegment
        }
      }
    }
  }
}

The schema InstanceMetadata consists of:

Property	Type	Description
`locales`	[String]	Specifies the locales where the content exists.
`expired`	DateTime	A datetime that specifies when the content instance expires. If the date is a time that as passed, the content be filtered from public queries.
`container`	String	The `key` of the content instance that contains this instance.
`owner`	String	If the content is in an asset to another content then this specifies the owning content.
`routeSegment`	String	Specifies the route segment for this content instance. For components or blocks that are not routable, this is
`lastModifiedBy`	String	Specifies who last updated the content version.
`createdBy`	String	Specifies who created the first version in the current locale.
`path`	[String]	Specifies the hierarchy of containers.

MediaMetadata

For media content instances, _metadata can be cast to MediaMetadata, like the following:

query MimeTypeQuery {
  _Media {
    items {
      _metadata {
        displayName
        ... on MediaMetadata {
          mimeType
        }
      }
    }
  }
}

The schema MediaMetadata consists of the following:

Property	Type	Description
`thumbnail`	String	The URL for a thumbnail of the media content instance.
`mimeType`	String	Specifies the mime type for the media content instance.
`content`	String	Contains extracted content from the media instance. See Text extraction field.
