semantic annotation of XML docs

Working on (ontology-mediated) integration of XML based tourism standards 
I'm doing a survey on existing approaches, tools, projects dealing with 
semantic annotation of XML documents. Having XSDs as input and following 
the bottom-up approach a conceptual data model will be created (manually or 
semi-automatically). The underlying schemas should be then transformed into 
either a canonical XSD or RDFS representing the data model ... and the XML 
instances accordingly.

Any hints to related work will be appreciated!

Thanks!
