Style normalization for canonical X-to-O mappings

An X-to-O mapping takes an XML schema as input and returns an object model as output; this object model is meant for programmatic, schema-aware access to XML data. The provision of X-to-O mappings involves various challenges; one of them is addressed by the present paper: variation in style of schema organization, which should not unduly affect the outcome of X-to-O mappings. We devise transformations for style normalization (and conversion); these transformations operate at both levels of the X-to-O mapping: schemas and object models. An important byproduct of the present work is to showcase functional OO programming as a viable setup for devising software transformations.
