Abstract:
In a computer network system having storage means tor source data and means for identification of said source data, a method for converting said source data of an element of interest conventionally presented in a first visual format and which is part of a mathematically regular expression into a canonical representation for rendering said source data in alternative formats, including aural formats and a second visual format, said converting method comprising:retrieving from a source said source data as two-dimensional data of mathematically regular expression form into said storage means; locating a unique container of the element of interest within a parsed tree of the mathematically regular expression; thereafter following a unique local route of the element of interest within the parsed tree to obtain a signature of the element interest, said signature being said canonical representation, said signature comprising said unique container and said unique local route; and storing said signature in said storage means for later use in retrieving and rendering a value of the element of interest.
