Document Object Model

The Document Object Model offers two levels of interface implementation: DOM Core, which supports XML and is the base for the next level, and DOM HTML, which extends the model to HTML documents. Here are some highlights:

• Any HTML or XML element (with the possibility of a few exceptions) will be individually addressable by programming.
• The specification will be language-independent. The specification, when available, will be described using the interface definition language (IDL) from the industry open standard CORBA.
• In addition, the interface will be described in terms of the Java programming language and ECMAScript, an industry-standard script language based on JavaScript and JScript.
• DOM is not to be confused with Microsoft's Component Object Model (COM) or Distributed Component Object Model (DCOM). COM and CORBA are language-independent ways to specifiy objects and could be used to create DOM objects (documents) just as specific languages like Java could.

Progress of the Document Object Model specification can be followed at the W3C Web site.
