Digital preservation strategies depend - to
some extent - on the creation, capture and
maintenance of suitable metadata:
"Preserving the right metadata is key to preserving
digital objects" (ERPANET Briefing Paper)
"It's all about metadata" (Kelly Russell, ca. 2000)
Metadata fulfil various roles, e.g.:
Within a digital repository, “metadata accompanies
and makes reference to each digital object and
provides associated descriptive, structural,
administrative, rights management, and other kinds
of information” (Clifford Lynch, 1999)
