Understanding HealthVault Data Types
A comprehensive list of all HealthVault data types is available from the HealthVault developer center at http://developer.healthvault.com/types/types.aspx. Each type has properties that determine to a great extent how items are created and used. To understand a type better, let’s take a deeper look at the example of the Weight Measurement type.
Type Properties
Figure 4-6 shows
the properties of the Weight Measurement data type that are common to
every data type from the HealthVault developer center (http://developer.healthvault.com/types/type.aspx?id=3d34d87e-7fc1-4153-800f-f56592cb0d17).
Each HealthVault type has a unique identifier; this
id is used by the HealthVault APIs to identify the
type. In the case of Weight, it is 3d34d87e-7fc1-4153-800f-f56592cb0d17.
A type sets the uncreateable property to true if no
application can create such a type in a user’s HealthVault record; a
good example of this is the Basic type. The immutable
property is true if no application can modify or update an instance of
that type in the user’s HealthVault record; a good example of this is
the CCR type. The property singleton is true if only
one instance of that type can exist in a user’s HealthVault record; a
good example of this is the Basic Demographic type.
