Overview of The Content Model for Web Applications

The content model is derived from an examination of use cases developed for the web application. This model contains structural elements that provides a view of content requirements for a web application. Structural elements include content objects like text, images, audio, video and photographs.It also contains analysis classes which cover attributes that describe it, operations that effect the behavior and collaborations.

A content object is any item of cohesive information that is to be presented to an end-user. These content objects are extracted from use cases. Content can be developed before the web application implementation, while the web application is being built or long after web application is operational.
The web engineer meets the person who has designed the use case and obtain a more detailed understanding of what descriptive and pricing information means. The descriptive information includes a paragraph of general description of component, photograph of component, a multi-paragraph technical description of component, a schematic diagram of component and a thumbnail video that shows how to install the component.

Content objects with a brief description of each object is more than enough to define the requirements for content that must be designed and implemented. In some cases, a data tree is used to represent a hierarchy of content objects. The content model may contain entity relationship diagrams that describes the relationship among content objects.
