Dossia is an open source project and supporting organization that welcomes developer collaboration in order to facilitate an ever growing ecosystem of health applications. Dossia is, of course, always looking to expand this ecosystem, and therefore publicly released the Dossia API to allow for other application developers to integrate with Dossia.

Dossia offers a Personal Health Platform, which aggregates users' health information into a convenient and safe Web-based Personal Health Record. From this Personal Health Record, users are not only able to utilize their data, but they also have access to personalized health tools that help them improve their health, manage their health conditions, and help them to better navigate the healthcare system.
