Passing Preformatted HealthVault data on a WPD device

In the latest versions of HealthVault Connection Center, we have enabled a new type data interaction between device drivers and HealthVault Connection Center.  Some devices may store data on the device as a native HealthVault XML file, as a result it is not necessary to convert the HealthVault XML into WPD properties and back to HealthVault XML.  So we have implemented a "data taxi"  feature in HealthVault Connection Center that enables drivers to directly expose the XML's to be uploaded into HealthVault.  This feature allows for customized data types, as well as non-WPD supported data types to be sent to the HealthVault platform.

When this device is connected to the PC, its WPD driver allows Connection Center to find the items and identify them as preformatted HealthVault Data.  Next, Connection Center will transfer the data (bypassing the usual WPD to HealthVault transforms that are required for data not already in HealthVault format).  From this point on, the data items are uploaded in the usual way for Connection Center.

Attached is a document that discusses how you would be able implement this in your drivers.
