Abstract
A challenging problem in Web engineering is the integration of XML data sources. Even if these data sources conform to schemas, they may have their schemas and the correspongind XML documents structured differently.
In this paper, we address the problem of integrating XML data sources (a) by adding semantic information to document schemas, and (b) by using a query language that allows a partial specification of tree patterns. The semantic information allows the grouping of elements into the so called schema dimensions.
Our approach allows querying data sources with different schemas in an integrated way. Users posing queries have the flexibility to specify structural constraints fully, partially or not at all. Our approach was initially developed for arbitrarily structured data sources [1]. Here, we show how this approach can be applied to tree-structured data sources that comply to schemas.
