Database of EEG/ERP experiments: technical report no. DCSE/TR-2010-04

This work summarizes problems occurred with storing data from EEG/ERP experiments. It address problems with EEG/ERP data formats, metadata description or sharing experiments between laboratories. Work shortly introduces background of EEG/ERP experiments and laboratory equipment. Existing formats including EDF, ARFF, WEKA or VDEF are presented with description of its advantages and difficulties. Difficulties of neuroscience databases and existing databases are also presented. There is an organizatoin called INCF that recommends how to make databases sustainable, those recommendation are presented. Because the internet is suitable medium for sharing of experiments and the semantic web provides possibilities how to represent metadata of experiments, work is either focused on the semantic web technologies. It describes common languages with their interpretative capabilities and difficulties. Since nowadays data are usually stored in the relational databases or represented by object oriented model hence possibilities how to represent and semanticaly describe sense of data by relational or object-oriented model is presented in comparison with the semantic web model. Mapping between those representations is analyzed together with description of existing tools. In the last part of developed portal is presented
