What is meant by long-term digital preservation?
There are several definitions of the concept of long-term digital preservation.
The various definitions are often linked to the type of material. On the
website of the LDP Centre (Centre for
long-term digital preservation) there is a following definition (originally in Swedish):
"Long-term preservation: A time period longer than the lifetime of the
system (hardware and software). Preservation in view of 'the next generation.'
Today the average life span of digital systems is considered between three and
seven years. "
Are storage and preservation same thing?
When it comes to digital preservation issues sometimes people uses both
concepts of preservation and storage. It also happens that "long-term
storage" of data is mentioned, which can be rather confusing. Storage as
the term is meant for technical storage. The storage of digital information
does not secure that future users can reach it, understand it and put together content.
Storing a digital photography or a scanned image gives no guarantees that, for
example, colour reproduction will be preserved for the future. For it requires,
among other things, to add the relevant metadata. Digital information created
through digitisation must be created in such a way to prevent from the future
lost of data when format or storage media has to be changed.
