ListenLog

The ListenLog is a consolidated and documented history of an individual's online listening activity. It is simply a recorded activity log, in a standard and open format, capturing an individual's listening actions from multiple online applications. The ListenLog is unique in that its aim is to give the user the ability to accumulate and control the use of their listener activity data. The data is the user's. It does not belong to any vendor or intermediary. The user alone should have control over where the data lives, what applications write to it, what gets logged, who to share it with, and how it can be used. The ListenLog concept was devised in part for the Public Radio Tuner iPhone project, where it will likely be first introduced.
