SPS (Simple Project Syndication) is a dialect of XML for project syndication over the Internet. It proposes an open schema for the organization of information flow between people, documents, and tasks in a distributed ecosystem rather than a hierarchical one.
SPS Sample (XML)
SPS Schema (XSD)
Open-tasking (2004-2005) was an experimental web application that utilized the SPS schema. It enabled people to create and manage tasks that can be altered by other people to include more detail. In Open-tasking, people collectively designed vertically deep or horizontally wide projects based on other people’s skills. The distributed and open architecture of the Open-tasking system enabled people to manage their own complexity, so as the project develops, a worker becomes a manager and vice versa.
