Introduction General model of XML database integration
Input XML query, input XML data, output XML data Rules, constraints, mappings Metadata
Based on XML standard format, XDD combines all tasks of framework tightly and makes it easily to manipulate data
Reduce time and effort of programmers and users and syntax errors

XML Declarative Description*
XML Declarative Description (XDD) is XML-based information representation
Ordinary XML expressions (ground XML expressions)+ variables = Non-ground XML expressions
Enhancement of expressive power and representation of implicit information
XML clauses of the form H ← B1, … , Bm, C1, …, Cn
Able to express conditions, constraints*Wuwongse, V., Anutariya, C., Akama, K., and Nantajeewarawat, E. XML Declarative Description (XDD): A Language for the Semantic Web. IEEE Intelligent Systems, Vol. 16, No. 3, (2001) 54-65
