| Currently, XML is de-facto a standard meta-format for data exchange. When software components exchange XML data, validation of incoming XML documents is an extremely important task. Therefore, it is necessary to specify a set of integrity constraints XML documents must satisfy. For this, various languages such as Schematron or XQuery already exist. However, a problem occurs when XML schemas of the XML documents evolve in time - which is very frequent in practice. In that case, integrity constraints expressed over an old version of the XML schema must be adapted to suit the new version. Today, this must be solved manually.
The aim of this thesis is to study possibilities of automation of propagation of changes in XML schemas to integrity constraints. The author will analyze current approaches, methods and tools in this area. Then, he will propose his own solution which may be a combination of existing ones or completely new solution. He will also implement his proposed methods and will present some experiments on real XML documents, schemas and integrity constraints. |
