Module-based multimedia document model: basic principles and software architecture

This paper describes an approach to multimedia documents modeling. The approach allows a non-programming user to compose pages from objects of different types (blocks) and to install new types of objects (modules) made by third-party programmers. We propose original methods for document version comparison and multimedia document indexing and searching. The paper describes an architecture of a Content Management System for the model proposed; the focus is to provide software portability and backward compatibility. We elaborated two software products using this architecture: Fuzzle CMS, multimedia CMS for Flash websites, and FLAscheme, the embeddable business diagram editor.
