In the audiovisual domain, the Class EditorialObject transforms a
commissioned concept into an editorial definition of a MediaResource before fabrication (in
the Production Domain) and Distribution (in the Distribution Domain). An EditorialObject is a
set of descriptive metadata summarising e.g. editing decisions. An EditorialObject can also be
a part of an EditorialObject, which is defined by its start time and duration. An
EditorialObject can also be a group of EditorialObjects. For example a series composed of
episodes is defined as an EditorialObject.
