Betr.: RE: Bib-2 and the DC-Lib

Kevin,

I think you are right with your concern about interoperability between DC-Lib and Bib-2. As soon as you start indexing DC-Lib records what are the access points for the index? It seems rather obvious to me to use the DC-Lib names also as access points. As Z39.50 is also going to use XML as valid record syntax and more and more records will be DC-Lib in XML, I would like to suggest that Bib-3 = DC-Lib.

I appreciate that the Bib-2 attribute set is mainly designed for searching
MARC databases. The DC-Lib Profile is however designed, amongst other things
"to expose MARC data to other communities (through conversion to DC)".
DC-Lib record will need to be searchable via Z39.50, is it expected that
Bib-2 can be used for this or is it expected that another attribute set will
be created for this purpose? If the latter is the case ignore the following.

I have been informed that the latest version of DC-Lib is at
http://www.loc.gov/marc/dc/library-application-profile_200204.html. 

i) DC-Lib uses DC CREATOR, CONTRIBUTOR and PUBLISHER however they also
defined a qualifier called DCMI Agent Detail which can be family name, given
names, name, affiliation location, description, date time and identifier.
In Bib-2 there are 4 different structural qualifiers for NAME.  How could
Bib-2 be used to search for a family name in a document described by DC-Lib?

ii) DC-Lib for RESOURCE TYPE uses DCMI Type Vocabulary
(http://dublincore.org/documents/2000/07/11/dcmi-type-vocabulary/) as
qualifiers to Resource Type, these are not included in Bib-2.

iii) DC-Lib and Bib-2 for SUBJECT both have the content authority (encoding
schema in DC-Lib) of LCSH, LCC, MeSH and UDC.  DC-Lib also has DDC and bib-2
has 18 additional content authorities.

iv) DC-Lib uses coverage/temporal for duration and coverage/spatial for
geographic referent.  Coverage/spatial includes using the Thesaurus of
Geographic Names.

v) The DC-Lib DATE has some qualifiers that are not in Bib-2 e.g.
date/modified how would this be searched for using Bib-2?

etc etc etc

I expect Bib-2 will be used mainly for searching for physical items and
DC-Lib to be used mainly to mark up digital items.  However I expect that
librarians will want to carry out one search in a hybrid library.  I accept
that much can be done by mapping between Bib-2 and DC-Lib but remain
concerned that the development of DC-Lib in isolation of Bib-2 will cause
unnessary interoperability problems.  Am I right to be concerned?  I can
find out what the DC-Lib List view is on Bib-2?

You and your colleagues at BL obviously have more expertise in DC-Lib than I
do.  Therefore, I would welcome your input into this issue.  Could you
please be more explicit on your concerns and identify which are the access
points you have identified as being extended in different ways in Bib-2 and
DC-Lib, describe the nature of the documents and databases that you envisage
will be described using the  DC-Lib metadata elements and  spell out the
problems that you foresee will be encountered.

Thanks,
Barb

I suggest you look at
http://dublincore.org/documents/2001/10/12/library-application-profile/ 
which triggered my interest in this debate.  I'm not sure that what is being
included in DC-Lib should go into the XD Attribute Set.  DC-Lib seems to be
profiling additional data elements that can be used in the library community
and therefore shouldn't go in the XD set.  My concern is that Bib-2 is
extending the access points in a different way to DC-Lib and this is likely
to cause problems searching for documents described using the DC-Lib
metadata elements.

I'd be glad to give it away or maintain it myself.  I've not been following
Dublin Core activities, so I'm not aware of any divergences.  Let me know
what you want and I'll take care of it.
