....anybody that referenced that document minor changes in details are difficult to be recognized without the help of difference engines [1, 2, 3] Since a removed or modified document is worthless as a reference some solution to the broken link problem is necessary. Although there are several efforts [4, 5, 6, 7] and therefore several mechanism, e.g. removal of the link from all referencing document, are employed to solve this, they still have not been stablished. For example the reading of most online References of the former WWW conferences is impossible since a huge number of links already expired. If ....

....copyright into account. Probably consensual agreements with the referenced authors provide a suitable solution for this problem. 6. Related Work In this section, a short overview about similar concepts will be given. On the one hand, one can concentrate on systems that try to preserve links [16,17,18]. Their problem arises from the modifications that have to be implemented in the server software as well as in the used data transfer protocols. Furthermore, they cannot solve the problem that will occur when a linked document is not available online anymore. On the other hand, we have to ....

....intermediate solutions. The Persistent URL (PURL) scheme from the OCLC is one such approach which introduces a level of indirection into URL addressing [PURL] A PURL identifies a logical location of a resource which is then mapped to the real location using the HTTP redirect directive. WebLinker [Aimar95] is a similar scheme which uses Local Resource Names (LRNs) as intermediaries to URLs. All resources at a particular site are described in terms of their LRN which is mapped to the URL upon access. The remainder of this section describes two more ambitious schemes, illustrating their relationship ....
