Yes, but ... not the geographic/chron/typeformat names.
I've copied from the dc site only coverage and subject;
do note that Subject is intended ONLY for "topic of the
content" - and as I remember topic means only thematic
content, not e.g geographic content.

So what is needed here is to have LCSH as acceptable
authority list for Coverage.


Element: Coverage

            Name:        Coverage
            Identifier:  Coverage
            Definition:  The extent or scope of the content of the resource.
            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.Element: Subject

            Name:        Subject and Keywords
            Identifier:  Subject
            Definition:  The topic of the content of the resource.
            Comment:     Typically, a Subject will be expressed as keywords,
                         key phrases or classification codes that describe 
a topic
                         of the resource.
                         Recommended best practice is to select a value from a
                         controlled vocabulary or formal classification scheme.
