        For Richard Rinehart's questions about tagging object type and
media, I have been counting on even the current EAD accomodating
item-level genre and physical description.  Since it looks like the <DID>
elements can't contain any of the Phrase-level ACCESS elements, maybe
something to fix not just for GENREFORM? Janice and Mary realized that
<UNITTITLE> can't contain things like <PERSNAME>.

        (I don't recall trying to exclude these access elements from the
DID elements; seems to be result of how the phrase-level elements worked
out?  Just set me straight if I've mis-remembered.  I don't know that I'd
always tag as specifically as some of the following examples show, but
don't remember trying to prevent others from doing so.)


Here's what I'd imagined would work:

A basic approach, comparable to a FULL MARC 300 field, that could be
"labeled" as "Physical description."  (Sometimes, only say "15 photographs")

<EXTENT> 1 print (poster) on wove paper : color lithograph ; 80 cm x 30 cm
<EXTENT/>


A heavier content designation, to flag the object and media types by
adding the <GENRE> element as desired; like tagging a <PERSNAME> within a
<UNITTITLE>--

<EXTENT> 1 <GENRE...>print </GENRE...><GENRE...>(poster)</GENRE...> : color
<GENRE...>lithograph</GENRE...> ; 80 cm x 30 cm </EXTENT>


Alternative approach:

<UNITTITLE> Uncle Same Wants You
<UNITDATE> 1916?
<EXTENT> 1 print : color lithograph ; 80cm x 30cm </EXTENT>
<GENRE...>Poster</GENREFORM>
<GENRE...>Lithograph</GENREFORM>


Last thought, to be sure I understood: Your message suggests that one EAD
element would be adequate starting point?   (Looking at the categories for
description of works of art, there are a lot more 'elements' (e.g.,
Facture;  Measurements--dimensions, extent, shape, scale; Materials--role,
name, color).
