Module: Reading available information from files

Prerequisites: executable with java 1.5 and higher on Linux system without GUI/X

The aim is to develop a class that extracts all human readable information from files and provides them in a structure and data type suitable for further processing.

For suitable file types, a preview (thumbnails for images/videos) should be generated.

The corresponding API documentation should be elaborated using javadoc.

Suitable structures means: file size in data type long, file name in string, ID3-tags, EXIF, RIFF, AVI in objects that correspond to the format specifications.

The class and the structure have to be modularly expandable in order to be able to add the processing of new file formats and the providing of information in other data types easily.
