Abstract: A system architecture for linking one or more derived objects to existing data objects in a data structure can be organized in a variety of forms. A method for establishing the architecture may include linking first and second data objects. linking first and second data objects. The first and second data objects may be associated with corresponding first and second pluralities of properties. The method may include receiving a first user limitation associated with at least one of the first or second pluralities of properties and receiving a second user limitation associated with at least one of the first or second pluralities of properties. The method can include deriving a conclusion object comprising a third plurality of properties comprising a subset of one or more of the first or second pluralities of properties and linking the conclusion object to the first and second data objects.

Abstract: A method of media content discovery and playback, the method including receiving a query for media content items from a search client, the query including one or more user subscriber group identifiers and a plurality of search criteria, filtering a plurality of available media content items according to the query to generate a list of matching content items among the plurality of available media content items, returning the list of matching content items to the search client, receiving from the search client a selection token with a content item to subscriber group mapping, providing the token to a user rights manager, receiving a signature authentication from the user rights manager, and issuing a playback key to the search client.

Abstract: A system architecture for linking one or more derived objects to existing data objects in a data structure can be organized in a variety of forms. A method for establishing the architecture may include linking first and second data objects. The first data object may include a first plurality of properties, and the second data object may include a second plurality of properties. At least one of the second plurality of properties may be based on the first plurality of properties. The method may further include receiving, by a computer, a user limitation of a property type that is associated with the at least one of the second plurality of properties. The method may include deriving, based on the user limitation, a new object that includes a third plurality of properties. The third plurality of properties may include a subset of one or more of the first and second pluralities of properties. The new object may be linked to the first and second data objects.
