Abstract
At the heart of most successful open source projects is an emphasis on open
architecture -- at least one mechanism that allows the product to be utilized as
a support network for unanticipated extensions and independently motivated
functionality. Such extensibility mechanisms allow an open source project to
decentralize its evolution and take advantage of Internet-scale collaboration.
However, they can also be a source for unnecessary complexity and hidden
barriers to entry.
Representational State Transfer (REST) is an architectural style that I
developed to describe and redefine the World Wide Web. The essential
constraints of REST are designed to promote the development of open
architectures within Web-based applications, such that the resulting resources
are reusable across independently developed systems (today, we call these
"MashUps"). The same principles can be used to design other open
architectures, though not necessarily with the same constraints. This talk will
focus on applying principled design techniques to the design of open
architectures, as demonstrated by various examples from successful open source
projects.
