Abstract
An XML based type-definition language for declaring content-index for WinFS Types is provided. Content-index declarations can be specified for the Item type as well as it's sub-entities like Fragments, etc across Item type hierarchies. The properties of WinFS types in the schema are marked for content-indexing by the schema designer. Installing the content-index definitions includes parsing content-index definitions in the schema, generation of appropriate SQL statements for data extraction and storing the SQL statements.
