Description of the Application Area and given Dataset

Application Area Analysis

Das Anwendungsgebiet befasst sich mit der Visualisierung eines MP3 Archivs und dessen ID3 Tags, wie zB Artistname, Year, Album etc.
ID3 tags are a way to store information about an MP3 file within the file itself. Originally ID3 tags held just this basic text-only information about a music file. They were a standard size and held standardized information.
Die Besonderheit besteht darin, eine gute Umsetzung der Visualisierung zu schaffen, damit große Mengen an Informationen übersichtlicher und benutzerfreundlicher werden.
