Here is the BAA for LifeLog.

The Information Processing Technology Office (IPTO) of the Defense Advanced Research Projects Agency (DARPA) is soliciting proposals to develop an ontology-based (sub)system that captures, stores, and makes accessible the flow of one person's experience in and interactions with the world in order to support a broad spectrum of associates/assistants and other system capabilities. The objective of this "LifeLog" concept is to be able to trace the "threads" of an individual's life in terms of events, states, and relationships.

LifeLog technology will support the long-term IPTO vision of a new class of truly "cognitive" systems that can reason in a variety of ways, using substantial amounts of appropriately represented knowledge; can learn from experiences so that their performance improves as they accumulate knowledge and experience; can explain their actions and can accept direction; can be aware of their own behavior and reflect on their own capabilities; and can respond in a robust manner to surprises.
