Many important metadata properties of an Asset are stored in a raw form and cannot be displayed “as is”. Asset Share Commons introduces the notion of a computed property to solve this issue. A computed property is an abstraction of a raw metadata property that includes a small amount of logic to display in a human friendly format.
For example the size of an asset is stored in the metadata property jcr:content/metadata/dam:size and the raw value is stored in bytes and could have a value of 28358905. The computed property File Size displays 28.3KB.
