ORG Microsoft Research Title BIO I'm the architect for Metadirectory and Active Directory at Microsoft. My goal: a simple Identity System for the internet so apps can easily access the interpersonal realm of people, places, things and events - something that looks cool, is cool. I was co-founder and CTO of ZOOMIT, where I invented and helped explain and popularize metadirectory, now a dominant factor in the directory industry. We shipped the first metadirectory product in '96 and were acquired by MS in 99. Earlier, I was a slave of the ISO/CCITT, building transport, session, presentation, association, RTS, X.400, and X.500 by creating programs that wrote programs. I was rescued by the "Simple" in SMTP, later learning to avoid and sometimes ride tidal waves.
