Draft In Progress, 4/2002
|
- General
- DLDD is a core set of elements
that are mappable both to
and from MARC21 and Dublin
Core
- The DLDD will grow only as
required, as new elements
are needed for Columbia Digital
Library projects
- Relationship to MARC21
- In principle, any MARC21 data
element may be incorporated
into DLDD
- DLDD may have less granularity
in some elements than MARC21,
and more granularity in others
- DLDD is convertable into and
out of MARC21, though possibly
with some loss of content
designation
- DLDD does not MARC21 support
Alternate Graphical Representation
($6)
- DLDD does not include subfields;
instead, subfielded elements
are broken out into separate
fields that are linked and
sequenced as needed
- Special Features of DLDD
- The "role" of names
is always specified by the
"relator code",
including the MARC aspects
conveyed by the first digit
of 1xx, 6xx, 7xx
- [to come]
