evaluated against the five sustainability factors listed in the left columns.
The format scores positively for a given factor if that factor is considered
not to impede future digital preservation efforts; a negative score is
assigned when the factor is expected to hinder preservation. The accumulation
of negative scores results in an increasingly lower status for a format.
Therefore, a higher score indicates that a format's prospects for
sustainability are poorer than one with a low score. If no match on the
matrix is made, or if the MIME type is determined to be
application/octet-stream, a file undergoing assessment receives a score of 5.
