Dictionary Schema Overview

The dictionary schema is an XML representation of the IBM® SPSS® Statistics data dictionary. The data dictionary contains metadata that describes various properties of a data file. A copy of the dictionary schema, dictionary-1.0.xsd is installed with IBM SPSS Statistics. This section provides a general overview of the schema. Detailed schema documentation is provided in subsequent sections. The following figure shows a basic outline of the dictionary schema.
