Link integrity errors (i.e., broken links) occur when resources referenced by a link cannot be accessed. Reasons for broken links include removed, moved or renamed resources, network problems or unplugged devices and solution strategies for this problem are manifold .
In the course of this research project we research a new and comprehensive approach for fixing broken links that is applicable to Linked Data on the Web as well as to links between files stored in local file systems.
