Document Object Model (DOM)

The Document Object Model is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents. DOM 3 is the currrent working draft at W3C. DOM Level 2 HTML is currently the recommended level.

DOM Level 0 is loosely defined as "that which went before DOM 1" and has the DOM capabilities of Microsoft Internet Explorer 3.0 and Netscape Navigator 3.0 . Outside of this loose description and documentation by these two vendors, there is no standard reference.

DOM-T or transitional is a standard developed by SMPTE which is loosely defined as the intersection of the DOM capabilities of Microsoft Internet Explorer 3.0 and Netscape Navigator 3.0. It was designed to create content playable on both platforms and to be compatible with future versions of DOM.
