Yes, I'm getting the picture that librarians
are interpreting Subject as being as broad
as it is in LCSH; again, that is not the
way Subject was intended by the dc crew
(at least judging from my experience attending
a couple of these meetings).
The reason that Coverage became an element
was because:
- the definition given for Subject was understood
not to include geographic area or time periods
And the reason Type and Format came to the fore
is because again Subject was understood not
to include form/genre terms.
That is, "topical" = "thematic," and not anything
else.
When you look at Coverage, the dc-lite version is
always a word. The item is indeed 'about' that geographic
area - that is, it is a subject heading in the broad scope
of LCSH.
And as per your earlier message - what i figured
Rebecca intended for Coverage -place was:
marc 651|a
marc all other 6xx's |z
and correspondingly for Coverage - time:
marc 6xx|y
(?can you start a subject heading with a time period?
in that case the first field would be |a)

Mary,
I think that the next edition of the User Guide should make this
explicit. I am a member of the User Guide committee and the new
edition of the guide is awaiting the final decisions on the
interoperability qualifiers.
Currently, I think there is confusion concerning the geographic
place as part of a subject string. Adding to the confusion is the fact
that some implementations of DC, like CIMI, have add both topical and
geographic to both elements.
4.3 Subject from the current User guide does not show a geographic
heading and does only show “topical” terms. However, “Place” can be
topical and there are LCSH headings that do not provide an adjectival
qualifier to terms but rely on the $z for the geographic aspect..
I must admit, I did not assume from the guide that the geographic
aspect of the topic could not be added. The fact that LCSH is not
included as an Encoding scheme for Coverage but is an Encoding Scheme for
Subject, argues that the geographic aspect should be included in the
Subject Field. I think it would aid searching interoperability if all the
components of the LCSH string are included when searching multiple
databases that use LCSH:
Qualifiers for 'Subject':
Encoding Schemes:
LCSH
MeSH
DDC
LCC
UDC
Qualifiers for 'Coverage':
Element Refinements:
Place
Time
Encoding Schemes:
DCMI Point (place)
ISO3166 (place)
DCMI Box (place)
TGN (place)
DCMI Period (time)
W3C-DTF (time)
This is from the LC crosswalk for MARC and DC from the LC site:
http://lcweb.loc.gov/marc/dccross.html
Note that 651 is included but not the 650 $z - However 650 $x is not included either. I know that Rebecca wants to update it.
MARC 21:
Unqualified:
653 ##$a (Index Term--Uncontrolled)
Qualified:
Subject.Geographic: 651 #7$a (Subject
Added Entry--Geographic Name)
with $2=local (or other scheme as specified)
Subject.PersonalName: 600 17$a (Subject

with $2=local (or other scheme as specified)
Subject.CorporateName: 610 27$a (Subject

Name) with $2=local (or other scheme as specified)
Subject.ConferenceName: 611 27 (Subject
Added Entry--Conference
Name) with $2=local (or other scheme as specified)
Scheme=LCSH: 650 #0$a (Subject added
entry--Topical term)
Scheme=LCC: 050 ##$a (Library of Congress

I see your point, but that is not the way the Coverage
and Subject are defined; instead, Coverage notes that recommended
practice is to use words rather than numbers.:
"Element: Coverage
Comment: Coverage will typically include spatial location
(a place name
or geographic coordinates), temporal period (a
period label,
date, or date range) or jurisdiction (such as a named
administrative entity).
Recommended best practice is to select a value from a
controlled vocabulary (for example, the Thesaurus
of Geographic
Names [TGN]) and that, where appropriate, named
places or time
periods be used in preference to numeric
identifiers such as
sets of coordinates or date ranges."
and Subject notes that it is to be used for "topic of content."
