ISAN was created as an ISO (International
Organization for Standardization) standard, and designed
to respond to the needs of creators, owners, duplicators, distributors,
and consumers of audiovisual content, among others in the value
ISAN provides a unique, internationally-recognized, and permanent
reference number for each registered audiovisual work and distinguishes
between episodes, versions, languages, lengths, formats, and more.
ISAN is numeric (actually 96-bit/24 hexadecimal digits), so it can
be read by anyone on the planet, and easily processed by any system.
A state-of-the-art central registry of ISAN numbers and related
standardized metadata, based in Geneva, ensures that there is no
duplication of data.
