Nowadays, data-intensive applications face the problem of handling heterogeneous data
with sometimes mutually exclusive use cases and soft non-functional goals such as …

This paper identi es essential features of an XML query language by examining four existing
query languages: XML-QL, YATL, Lorel, and XQL. The rst three languages come from the …

We propose a framework for integrating data from multiple relational sources into an XML

We define a family of embedded domain specific languages for generating HTML and XML
documents. Each language is implemented as a combinator library in Haskell. The …

In information-integration systems, sources may have diverse and limited query capabilities.
We show that because sources have restrictions on retrieving their information, sources not …

The MIX mediator systems incorporates a novel framework for navigation-driven evaluation
of virtual mediated views. Its architecture allows the on-demand computation of views and …

The increased usage of mobile devices coupled with an unprecedented demand for
information has pushed the scalability problem of pull-based data service to the focus. A …

An increasing number of web sites have their data extracted from relational databases.
Several commercial products and research prototypes have been moving in the direction of …

Information integration systems provide facilities that support access to heterogeneous
information sources in a way that isolates users from differences in the formats, locations …

Digital library mediators allow interoperation between diverse information services. In this
paper we describe a flexible and dynamic mediator infrastructure that allows mediators to be …
