Data model

Health data in a person's HealthVault record is represented by a thing, which is the health data encoded in XML. Each type of health data is represented by a different thing type. When necessary, a new version of a thing type may be introduced with a different schema. HealthVault also defines a set of common data structures used to describe each thing type.
