We discuss a proposal for the implementation of the model management operator
ModelGen, which translates schemas from one model to another, for example from object …

In this paper we introduce the concept of Technical Space (TS) to refer to technologies at a
higher level of abstraction. Some technical spaces can be easily identified, eg the XML TS …

An adequate level of trust must be established between prospective partners before an
interaction can begin. In asymmetric trust relationships, one of the interacting partners is …

Data integration is frequently performed between heterogeneous data sources, requiring
that not only a schema, but also the data modelling language in which that schema is …

In pattern classification, features are used to define classes. Feature selection is a
preprocessing process that searches for an" optimal" subset of features. The class …

We describe MIDST, an implementation of the model management operator ModelGen,
which translates schemas from one model to another, for example from OO to SQL or from …

In this paper we present and study the problem of schema exchange, a natural extension of
the data exchange problem in which map**s are defined over classes of similar schemas …

A person working with diverse information sources—with possibly different formats and
information models—may recognize and wish to express conceptual structures that are not …

Abstract Models for conceptual design of data warehouse schemas have been proposed,
but few researchers have addressed schema evolution in a formal way and none have …

In this paper, we illustrate an approach to the translation of Web data between
heterogeneous formats. This work fits into a larger project whose aim is the development of …
