To create a new custom data source that uses an extension adapter, begin in the usual way by clicking New Data Source, selecting the name of the extension adapter from its alphabetical place in the New Physical Data Source window, assigning it a name, and so on. See “Working with Data Sources” of the TDV User Guide for details.

The set of properties available for data source instances connected using a given extension adapter depend on the configuration of that adapter. (Extension Adapter Configuration, describes this.)
