A machine based tool and associated logic and methodology are used in converting data from an input form to a target form using context dependent conversion rules. In particular, a frame-slot architecture is utilized where a frame represents an intersection between a contextual cue recognized by the machine tool, associated content and related constraint information to specific to that conversion environment, whereas a slot represents an included chunk of information. An exemplary conversion system () includes a parser () for use in parsing and converting an input stream () from a source () to provide an output stream () in a form for use by a target system (). To accomplish the desired conversion, the parser () uses information from a public schema (), a private schema () and a grammar (). The public schema (), private schema () and grammar () may include conversion rules applicable to less than the whole of a subject matter area including the input stream ().
