An Initial Digital Identity Taxonomy

Thanks to Jaco Aizenman and Luke Razzell for feedback. I thought I'd go one step further and get my initial digital identity taxonomy (more accurately, glossary) laid out as a page on this website:

http://blog.onghome.com/glossary.htm

I decided to use the term interaction instead of transaction to avoid confusion with database transactions.

Any feedback would be appreciated.

Update (April 24, 2005):
Thanks to Jaco Aizenman and Jack Krupansky for their comments. I decided that Jack was right and to call this collection of definitions a glossary, instead of a taxonomy.

Update (April 27, 2005):
o Slimlined glossary by simplifying definitions, and taking out what's not necessary (e.g. entifier).
o Luke Razzell has updated the entries on digital identity on Wikipedia. I'll join in if I can find a few spare cycles.
o Jack Krupansky linked back to the glossary at http://www.basetechnology.com/nature_of_identity_links.htm.
o Kaliya Hamlin also linked back at http://identitywoman.net/archives/2005/04/digital_identit_2.htm.

Update (May 4, 2005):
o ChangHee Lee linked back (in Korean) at http://guldook.blogspot.com/2005/04/digital-identity-glossary.html; but just to clarify, I'm not associated with PingID... I don't know Korean either.

Update (August 9, 2005):
The Berkman Center has some work on digital identity lexicon (http://cis-berkman.editme.com/Lexicon).
