Polyphony v. 1.5.5 (2010-03-04)
=================================

What is Polyphony?
------------------
Polyphony is a set of user-interface components to go along with the Harmoni
Framework. These components include a Wizard System, Repository access actions,
log-browsing actions, user-management forms, and a number of other user interface
components that may be useful for web-based software that is built on Harmoni.

Usage of Polyphony is not required for Harmoni usage, but most of the Polyphony
components rely on Harmoni.

Polyphony is currently used in the curricular applications built by the Curricular
Technologies group at Middlebury College: Segue 2 and Concerto.

About Harmoni:

The Harmoni Project is an effort led by the Curricular Technologies group at
Middlebury College to build an application framework and standards-based
infrastructure bus to support the rapid development and easy maintenance of
curricular it projects. The project is built entirely using PHP's OOP (Object
Oriented Programming) model, allowing the framework code to be easily extended and enhanced.

At the core of the Harmoni Application Framework is an implementation of The Open
Knowledge Initiative's (O.K.I) Open Service Interface Definitions (OSIDs). The OSIDs
are a standard service-oriented API that defines a broad set of services that are
germane to IT projects in the education field yet also fitting for broader uses.

Sitting alongside of the Harmoni services is the "Harmoni Architecture". The
"architecture" is a set of controllers and templates that coordinate configuration
of services, the proper execution of application actions, and any post-processing of
application output. The architecture is built on a popular module/action model, in
which your PHP program contains multiple modules, each of which contain multiple
executable actions. All you, as an application developer, need to write are the
action files, not the controller logic.

The "Harmoni Architecture" is separate from the Harmoni Services and either can be
used independently of the other.
