data property
Any additional information about the embedded content. Only used at this time to store OpenGraph metadata. This field will be null for non-OpenGraph embeds.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
