Beginning with the next release of the AdsML Framework, which is targeted for mid April, users will be able to convey the duration of an advertisement using a dedicated “Duration” element. Until now it was necessary to use a user-defined property for this purpose. Duration can be expressed in any desired unit of measure: seconds, minutes, hours, etc. The Duration element will be available wherever it is currently possible to describe an advertisement’s size.
This new feature is entirely optional and backwards-compatible.
