Component for extracting content-index data and properties from a rich structured type

Installing the content-index definitions includes parsing content-index definitions in a schema, generation of appropriate SQL statements for data extraction and storing the SQL statements. A run time infrastructure for extracting data to be content-indexed from the highly structured entity types is provided. This logic includes looking up the type of the item and its associated entities that need to be content-indexed, executing the corresponding data extraction code (SQL statements) and sending it to a protocol handler for content-indexing. Also included is an execution infrastructure for utilizing the generated SQL from the mappings to extract search properties from items.
