The canonical HTTP API for tiddlers: small chunks of content on the web.
Project originator, lead and community manager for a WSGI-based Python application originally created as a reference server side for TiddlyWiki; TiddlyWeb has since evolved into a robust generic content and data store with a pluggable architecture allowing multiple representations and storage systems.

Inverting the Social Web with Internet Banks of Content
The fundamental concept in an Internet Bank of Content (IBOC) is that rather than giving a piece of sociable content to a web service, a participant in the social web would upload or locate that content in their Bank and provide a URI to the service, called a presentation service. The bank holds the content in trust for the individual.
TiddlyWeb: HTTP for Tiddlers
Describes the lessons learned while developing TiddlyWeb as a resource oriented HTTP API.
The Computer as Tool: From Interaction To Augmentation
Describes a design approach wherein computers and computer applications are thought of as tools rather than interactive devices. This paper was instrumental in forming the Blue Oxen Way, a framework for a philsophy of collaboration.
Creating Conceptual Access: Faceted Knowledge Organization in the unrev-ii email archives
The email archive of the unrev-ii list is the basis for this ongoing project, to build an access tool for an email archive that also functions as a knowledge repository.
Hypertext and Knowledge Enhancement
A fun and rambling exploration of hypertext and knowledge enhancement driven by a hypertext tool specially created for the project.
