Organisation und Zusammenfassung quantitativer und qualitativer Messdaten im Rahmen des CORE-Organic QACCP Projektes

Summary

Projects which are dealing with the question of food quality (i. e quality management,
authenticity) usually evaluate measurements, which result from the application of
different methods, usually in different institutes, on the same samples. Usually each
method/institute evaluates its data and the overall findings due to the existing hypothesis
are condensed in the project report. The data remain at the institutes. When the
hypothesis develop, the data of the other partner institutes are not, or not easy accessible,
to test the new hypothesis. A numerical method comparison and a multivariate
statistics on the data is not possible. As a result of our BLE170 project, we included
the development of a data-organisation in the following BLE170/F project. This had as
the goal to merge the data from different methods/institutes in one data file which
should be accessible for evaluation by all the partners of the project. The question of
publication rights was connected to a Non Disclosure Agreement (NDA).Simple statistical
evaluations were done, like correlation between the methods, to check for
comparable methods. These results were accessible through a user/password protected
web site. In the Core-Organic 1885 project we are adapting the data integration
system to the needs of this project, upgrading the existing software from only developer
usable to a maintainer usable status. The work presented here describes how the
data integration is organised (data format, data merging and evaluation) within the
Core-Organic QACCP project.
