Domain data models

This section provides the details of the data structures used by the OpenTV Platform APIs.

The different structures are organised by business domain:

• Metadata retrieval.
• Recommendations.
• Account and device for subscriber management.
• Subscription entitlement.
• Timeshifting.
• User activity.

Reference Specifications defines data structures that identify specific items.

While the underlying data structure remains the same, APIs from different services may use a different syntax for some fields.
Such differences are highlighted in the data structure descriptions.
For example, for the Account structure and the field that carries the reference to its AccessPoint:

• For the SMSDomain APIs, the field is named accesspointSpecification and is a structure of type AccessPointSpecification (see AccessPointSpecification).
• For the SDP base and aggregate services APIs, the field is named accessPointUID and is a Long value with the corresponding UID.

Field values are not case sensitive. So settopbox and SetTopBox are both acceptable.
