Method and system for mapping between structured subjects and observers

A method of binding elements of a structured document to an observer structure includes obtaining the logical structure of a document. Nodes representing information contained in the document are mapped to an observer structure which can include both a user interface or a programming object. The user interface may be a graphical user interface including a display form of a grid-like structure to contain the structured document information. The data binding which maps the structured document information to the observer form may be directionally controllable such that any change made to the information at the observer may be reflected in the source structured document.
