Abstract
Abstract This invention is a method for annotating and redacting a final-form document archived in a computerized system where it is important that the fidelity of the final form document is preserved. More particularly, this method allows final-form documents containing objects such as texts, graphics and images to be annotated or redacted by other objects carried in the same data stream without compromising the integrity of the original document.

A method for storing documents and information associated with said documents, said method comprising the steps of: converting a document to a document data stream, said document data stream comprised of document data and a plurality of structured fields; converting information associated with said document to an information data stream; combining said document data stream with said information data stream to form a combined data stream, leaving said document data in said combined data stream unchanged; modifying at least one of said structured fields in said combined data stream by adding an include structure to indicate that said information data stream has been included in said combined data steam; and storing said combined data stream.
Claim 3
Dependent Claim
55 words
A method as in claim 1 wherein a first of said structured fields is associated with a first portion of said information data stream, and said first structured field indicates whether said first portion of said information data stream is an annotation of said document data stream or a redaction of said document data stream.

120 words
An apparatus for associating information with a stored document, said apparatus comprising: means for converting a document to a document data stream, said document data stream comprised of document data and a plurality of structured fields; means for converting information associated with said document to an information data stream; means for combining said document data stream with said information data stream to form a combined data stream, leaving said document data in said combined data stream unchanged; means for modifying at least one of said structured fields in said combined data stream by adding an include structure to indicate that said information data stream has been included in said combined data steam; and means for storing said combined data stream.
Claim 8
Independent Claim
120 words
An apparatus for associating information with a stored document, said apparatus comprising: means for converting a document to a document data stream, said document data stream comprised of document data and a plurality of structured fields; means for converting information associated with said document to an information data stream; means for combining said document data stream with said information data stream to form a combined data stream, leaving said document data in said combined data stream unchanged; means for modifying at least one of said structured fields in said combined data stream by adding an include structure to indicate that said information data stream has been included in said combined data steam; and means for storing said combined data stream.
Claim 9
Dependent Claim
55 words
An apparatus as in claim 6 wherein a first of said structured fields is associated with a first portion of said information data stream and said first structured field indicates whether said first portion of said information data stream is an annotation of said document data stream or a redaction of said document data stream.
Claim 10
Dependent Claim
200 words
An apparatus as in claim 6 wherein: a first plurality of structured fields comprises a plurality of "begin flags", each of said begin flags indicating the beginning of a portion of said document data stream corresponding to the beginning of a portion of said document: a second group of said plurality of said structured fields comprises a plurality of "end flags", each of said end flags indicating the end of a portion of said document data stream corresponding to the end of a portion of said document; a third group of said plurality of structured fields being "indicator flags", each of said indicator flags being associated with one of said beginning flags and one of said end flags, said indicator flags indicating specific conditions; and said modification of at least one of said structured fields comprising modifying a first of said indicator flags, said first indicator flag being associated with a first of said beginning flags and a first of said end flags, said modified indicator flags indicating that a first portion of said information data stream is to be associated with said portion of said document data stream corresponding to said first beginning flag and said first end flag.
Claim 11
