As mentioned above, the assignment or renewal of a guarantee of existence is an indirect statement about the relevance of a document. Documents with a long guarantee of existence seem more important than those with a shorter one. This might not apply to individual cases but on the whole it is absolutely imaginable.
One of the biggest problems within large information systems is to retrieve relevant information or, in other words, to separate the wheat from the chaff. Ranking mechanisms (or ranking algorithms) play an important role. They determine the order in which retrieved information is listed.
The incredible success of Google can be attributed to refined ranking mechanisms. Information is much more worth seeing if it is referenced by other websites which are in turn classified as worth seeing. Here, the realization that the linking of texts could be a relevant indicator for the importance of information was decisive.
In addition, the assured and indicated availability of information could be accepted as a criteria. Hence, it could be imaginable to consider the guaranteed availability of documents in ranking mechanisms. Whether this applies to search engines or to enclosed information systems is not important.
