Digital preservation is the ability to ensure digital contents and files are available for long time periods and can transcend technological obsolescence without loss of readability and accessibility.
The Unisa digital preservation mitigates against the risks of loss of digital materials.
Aims of Unisa digital preservation:
The file format identification is an important part of digital preservation. Knowing what type of file format, you have and what version it is, will assist with preservation planning for that digital object. It will also provide information on the types of software programs that can open and render the digital object. It is important to note that a program may be able to open a particular file format, but it may not render it correctly. This means that the look and feel could be altered, sometimes slightly and sometimes making it difficult to interpret. This is particularly true for older file formats that were created with legacy software programs. Be aware that legacy can mean only 10 years!
