Collection Relations [C ARC]

For managing collections it may be helpful to know the semantics of the collections' contents. A possible use-case would be the series - season - episode structure:

The topmost collection stands for the series.
The series collection contains one ore more collections denoting each season.
Each season collection contains multiple items - one for each episode.

The default VidiCore collection only “knows” the technical type of each child entry, i.e. a collection or an item. To store the semantics of each child the key-value metadata entry relation is used. It can contain the following values:

Value	Meaning
`isSeasonOf`	The child collection is a a season of the this collection.
`isEpisodeOf`	The child item (or collection) is an episode of this collection.

A season collection containing one episode item would look like this:
