The technology described herein is directed towards content rights data that are associated with content (a data item) to make that content selectively available or unavailable in responses by a data service to client requests. A client includes client content rights data in association with each request, (e.g., via a token), and the data service uses that client content rights data as query parameters (constraint criteria) in making a request for a data item. Client content rights data also may be used for accessing cached data. Availability constraints may include client location, brand, channel, device class and time (commence and cease). |

1. A method comprising:
maintaining content rights data in association with a data item; receiving a client request for the data item, in which the request is from an authorized client and includes client content rights data; and determining whether the content rights data maintained in association with the data item indicates that the data item is available to the authorized client, and if so, returning the data item, and if not, returning an indication of unavailability of the data item. |
