a quick look through:

http://arc.cs.odu.edu:8080/dp9/index.jsp
(for each repository: click on info, click on "ListSets")

shows that maybe 1/2 of the 60 DPs listed employ sets, and many of the
sets have the appearance of subject classification systems.

how many of them are "standard" is another question...  

to my end, http://techreports.larc.nasa.gov/ltrs/oai/ uses the NASA STI
Subject Categories:

ftp://ftp.sti.nasa.gov/pub/scan/SCAN-TOPICS

on the other hand, http://naca.larc.nasa.gov/oai/ has no subject
information, since NACA predates the NASA STI categories.  I've been
wondering if I should just declare all the NACA records in category 
"01 - Aeronautics (General)"; I'm not sure if that helps or hurts.

regards,

Michael
