A mediacard is an aggregation of all the information required to present a single-page view to the client. This includes information including (but not limited to):
-
The content to which the mediacard concerns.
-
Whether the content has a bookmark.
-
Whether the content is a favourite
The general structure of the mediacard aggregate is formed from the relationships shown below.
The diagram describes the content roots for the possible media card types. For example, a VOD item can be delivered by a Recommendation or by a Bookmark. This API enables the client to aggregate away / facade the calls to assemble the root content when building media card types.
By calling the described APIs, a client device is able to make a single API call with an input of content ID and from the response construct the full media card (limiting the number of calls required).
