D6.2, Methods for
data acquisition and transformation
Short Description:
The purpose of this document is to describe methods for homogeneous
access to data residing in information sources to be integrated, and to
select and adapt available research results for their realization from
the fields of information integration and agent technology. The data in
the sources are given in the raw data formats specified in Project
Report D6.1, and have to be transformed into an appropriate format for
internal integration use. In the course of this, the INFOMIX Source
Data Format (ISDF), which provides a uniform logical format of the
source data to the user, has to be taken into account, as well as an
internal integration data format, which is the one used by the internal
integration algorithms. Furthermore, the usage of methods and
techniques for information extraction from implicit representation in
this framework will be respected.
