For several years now, I've been giving talks on subject-centric computing with my talks on "federation". I've been amazed at how many people require that I define "federation". Now, it would seem that "Subject-Centric Computing" has come to have its day in the sun--likely through no efforts of mine, but still very satisfying. One of my earliest critics is now one of the loudest champions. Read Steve Pepper's slides
to see what I mean. The paper is a nice overview of the issues related to subject-centric (as compared to document-centric) computing, but glosses over what I consider the primary issue: subject identity.
Key take-home point: migrate from document-centric to subject-centric and you remove an impressive amount of sting associated with infoglut. My view: we miss something when we talk about documents; we are really talking about subjects entrained in those documents. I could say "It's the Subject, Stupid!", but I won't.
