摘要：
A method is disclosed to implement data management protocols using a projector. The method provides first information comprising data and metadata to the projector, where that metadata comprises data management protocols for said first information. The method then determines by the projector if the data management protocols designate a time interval. If the data management protocols designate a time interval, then the method determines, by the projector, that time interval, the current time, and if the current time is within the time interval. If the current time is not within the time interval, then the method does not permit presentation of the first information using the projector. Alternatively, if the current time is within the time interval, then the method permits presentation of the first information using the projector.
