ODA: A Study of Document Design
A document is considered as a textual record. A unit consisting of dynamic, flexible, nonlinear content, represented as a set of linked information items, stored in one or more physical media or networked sited, created and used by one or more individuals in the facilitation of some process or project. In ODA document architecture is defined as the set of rules for structuring interchanged document. The logical structure divides and subdivides the content of a document into increasingly smaller parts on the basis of the human perceptible meaning of the content e.g. into chapters, sections, paragraphs and figures. The layout structure divides the content into sets of pages, individual pages and areas within pages such as columns.
