SECOHealth is an international project that aims to understand and control the health of software ecosystems, where software ecosystems are interpreted as ecological ecosystems comprised of a population of living organisms (software projects and their communities of contributors). The goal is to (1) define a conceptual model of ecosystem health, then (2) determine health indicators capable of measuring the different aspects of such health, as well as determine events that affect the health of ecosystems; and (3) empirically validate these health indicators and events.
