The document describes a developer challenge hosted by Palo Alto Medical Foundation (PAMF) and Health 2.0 to leverage data from PAMF's linkAges system to better connect seniors in the community. The linkAges system captures senior profiles and needs and facilitates service matching and a timebank program. Entrants are asked to submit solutions for engaging users, tracking community growth, and optimizing service matching. A workshop will provide more information and the top 5 finalists will present prototypes to win prizes from $1,000 to $10,000. The goal is to activate communities and support successful aging in place.
