In this paper, we illustrate a preliminary approach to the
translation of Web data between heterogeneous formats. This work fits
into a larger pro ject whose aim is the development of a tool for the man-
agement of data described according to a large variety of formats used on
the Web and the (semi)automatic translation of schemes and instances
from one model to another. Data translations operate over XML repre-
sentations of instances and rely on a uniform representation of models
that we call metamodel. The metamodel shows structural diversities and
dictates the needed transformations. Complex translation can be derived
by combining a number of predefined basic functions performing XML
transformations expressed in XQuery. Practical examples are provided
to show the effectiveness of the approach.
