Metadata quality:
|
|
|
|
– |
Standards often
deal with metadata semantics, but
|
|
|
not always with
'content rules'
|
|
|
|
– |
Recent
experience with use of unqualified Dublin
|
|
|
Core by OAI data
providers suggests that
|
|
|
metadata quality
varies widely, e.g.:
|
|
|
|
– |
DC
underutilized, e.g. 5 of 15 elements used 71% of
|
|
the time, many
records have just 'title' and 'creator'
|
|
|
elements (Ward,
2003)
|
|
|
|
– |
Some quality
problems with records being imported
|
|
|
|
before their
refinement by libraries (Halbert, 2003)
|
|
|
|
– |
Authority
control, de-duplication, etc.
