Lists including standardized meta-information are connected to the main data fields. Down to this level, all data are considered to be metadata. From each sample one or more 'real' analytical data will be produced which can be found on the DATA level. From this field, data can be exported as a table or plotted. The parameters are gathered into parameter groups for a better overview.
Data types can be numeric, string or graphic.
The hierarchy of the model follows the typical route used to process samples and to produce analytical data. The main server, located in the computer center of the AWI, is connected through the Internet with the different external institutes. The clients, which are the personal computers of the scientists, are connected through the local network with the sub-server of the related institute. The mutual update of newly imported meta-information is made in the background through the network. In this case a mirror site has to be set up.
