The term "digital signature" is a metaphor that seeks to describe a particular use of public key cryptography by use of the well-known "signature" term. The political direction in most parts of the world is towards wide acceptance of electronic documents, and introduction of electronic signatures to replace handwritten ones.

The conclusion is that storage cannot be regarded as reliable for more than about 10 years. This may cause problems in particular to e-govemment but is probably sufficient in most cases.
