# `<data-about>`

The `<data-about>` element identifies the subject of a property when the subject isn't associated with the context in which the property is specified. The property itself is expressed by the `<data>` element. The `<data-about>` element handles exception cases where a property must be expressed somewhere other than inside the actual subject of the property. The `<data-about>` element is particularly useful as a basis for specialization in combination with the `<data>` element.
