As a follow up to Rebecca Guenther's not re Dublin Core mapping to MARC, 
her is an extract from a message I sent to Eric Miller re Dublin Core 
mapping to GILS:

 ------------------------
"I was very interested to see the comparison you have prepared between the 
Dublin Core and EAD, GILS and MARC ( 
http://www.oclc.org:5046/~emiller/DC/crosswalk.html#GILS ).

In the Canadian government work on GILS ( http://gils.gc.ca ),  we have 
introduced several new data elements to make GILS more suitable for 
describing individual documents.  They also bring GILS closer to the Dublin 
Core.  These have been incorporated into version 2 of the GILS Profile ( 
http://www.usgs.gov/gils/prof_v2.html ) but aren't present on your table. 
 For example GILS now has an "author" element which would map to 
"OtherAgent"; a "date of publication" which maps better to the DC date than 
"available time period"; "Language of Resource" maps to DC Language; "Cross 
Reference Relationship" has been added so that Cross Reference could map to 
DC Relation.

We also added "Language of Record" to GILS.  This is an element in the 
Canadian MARC format, though not in US MARC.  It is necessary in our 
bilingual environment where the description of the information resource may 
be in English or French.  The resource itself might be bilingual and would 
have two separate GILS records, one in English and one in French.  This is 
the pattern we follow in our cataloguing records as well.  You might 
consider the necessity for such an element in the DUBLIN Core if it is to be 
used beyond the English language community.

The one Dublin Core Element that we haven't yet introduced into GILS is 
ObjectType.  We hoped that Format would be sufficient but as we create 
records in our Canadian GILS Pilot Project we are discovering a need for 
distinguishing different types of resources e.g. services, collections, 
databases as well as individual documents or publications.  However, coming 
up with a logical list of Object Types is not easy.  We would appreciate any 
advice in this area from the designers of the Dublin Core or those 
experienced in applying it. "
 --------------------------------------

Rebecca Guenther's note gives some information on developing standard lists 
for Object Type or Resource Type.  Have other GILS users identified a need 
for this data element?  Has anyone developed a standard list?
