A tag sharing method and system. The method includes receiving by a computer processor, an audio/video data file and tag data describing different subject matter of audio/video data of the audio/video data file. The computer processor associates portions of the tag data with audio/video subsets of the audio/video data and in response the computer processor generates a modified audio/video data file including independent audio/video tags. Each audio/video tag of the independent audio/video tags includes an audio/video subset of the audio/video subsets independently stored with an associated portion of the portions of the tag data. The computer processor receives rule data comprising rules associated with allowing users of a social networking system to view each audio/video subset. The computer processor stores the modified audio/video data file and the rule data.
