Canonicalizing names (was Re: XSLT script for IMS)

I've been investigating the name formats used in the OCW xml files.  
I've attached a complete listing of the names as found using the 
following xmlstarlet command:

$ xml sel -T -t -m //Entity -v . -n *.xml | sort | uniq >namelist.txt

There are several names here that I would expect to cause trouble:

Gleason's Pictorial
Brown
United States of America
Smithsonian Institution
Glenn Ellison; Sara Ellison

Peters, W. T.
Prof. Joseph Ferriera, Thomas Grayson

The main two formats are "[honorific] firstname lastname[, appelation]", 
and "lastname, firstname [middlename or initial]", but these make up 
fewer than half of the records as a whole.

The OCLC web service does a pretty good job of finding matches in the 
"lastname, firstname [middlename or initial]" case, but only attempts 
word-matches in the "firstname lastname" case and fails completely if 
the honorific is left attached.  To do this yourself try for example 
searching for "Tom Leighton" (see MacKenzie's e-mail for the value of 
oclcservice):

$ wget "http://$oclcservice?method=getCompleteSelectedNameAuthority&name=Tom+Leighton&maxList=10&serviceType=rest&isPersonalName=true" -O leighton.tmp
$ xml fo leighton.tmp >leighton.xml


The results are in the second attachment.  As you can see, 'Tom 
Leighton' was matched against 'Wendt, Thomas Leighton' using word-match, 
whereas 'Leighton, Tom' would return a superior phrase-match.

The degerate cases shown above don't yield any useful results from the 
OCLC web service.

Cheers,
