Abstract
Technologies are described herein for relevance-based expiration of data. An initial expiration time for the data is computed based upon an expiration duration associated with the data. The expiration time for the data is periodically re-computed in order to extend the expiration time. A relevance value for the meeting data is computed and the expiration time is set as a function of the computed relevance value. The relevance value may be computed as a product of a user-settable relevance value for the meeting data and a dynamic relevance point for the meeting data. When the computed expiration time for meeting data has been reached, the meeting data is expired, such as through the deletion of the meeting data.
