Self-documenting
digital objects contain basic descriptive,
|
|
|
|
technical,
and other administrative metadata.

Self-documenting
digital objects are likely to be easier to
|
|
|
|
sustain
over the long term and to transfer reliably from one
|
|
|
archival
system to another, including a successor system.

|
LC
wants to take advantage of the trend towards
|
|
|
|
embedded
metadata for business reasons. Some
metadata
|
|
|
|
will
be extracted to support discovery and collection
|
|
|
management.

Examples:
|
|
|
|
|
JPEG
(.jpg) image files contain very scant metadata
|
|
|
|
|
EXIF
JPEG wraps JPEG compression with richer metadata
|
|
|
|
|
JPEG2000
(.jpx) image files may contain metadata boxes can
|
|
|
include
an extensive DIG35 record
