Schema Evolution publication categorizer

A systematic approach to the adaptation of XML documents and their DTDs is developed. The approach
facilitates the evolution of XML-based formats. There are two essential ideas. Firstly, changes
in the formats of documents are represented as stepwise transformations on the underlying DTDs.
Secondly, the corresponding migration of the XML data is largely induced by the DTD transformations.
The presentation focuses on concepts of format evolution, namely roles of corresponding transformations,
properties of the transformations, and expressiveness to implement the transformations.
