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:
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
o Kaliya Hamlin also linked back at

Update (May 4, 2005):
o ChangHee Lee linked back (in Korean) at; 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 (

I think that an interaction should by definition be between entities, each of which has an identity which may be anonymous.

I like what you've done, but I think it should be labelled as a "Glossary" rather than a Taxonomy. Maybe eventually it could evolve into an ontology, but it is what it is right now.

An ontology would be a full specification of a domain.

A taxonomy is a hierarchical categorization of entities in a domain based on chosen ontological characteristics.

A glossary is a brief set of definitions for terms within a domain.

Again, thanks for taking a stab at organizing what I call "The Identity Swamp".

I just introduce your glossary in my blog, I will translate it later.

After translating, let you know it.
