Abstract / Description:The growing use of XML in commercial as well as non-commercial domains to
transport information poses new challenges to concepts to access this
information. Common ways to access parts of a document use XPath-expressions.
We provide a transformation of DTDs into a knowledge base in Description Logic.
We use reasoning capabilities grounded in description logics to decide if a
given XPath can be satisfied by a document, and to guide the search of
XML-Processors into possibly successful branches of the document, thus avoiding
parts of the document that will not yield results. The extension towards object
oriented subclassing schemes opens this approach towards OODB-queries. In
contrast to other approaches we do not use any kind of graph representing the
document structure, and no steps towards incorporation of the
XML/OODB-processor itself will be taken.
