Abstract

Systems and techniques to create and use a reversible format document. In general, in one implementation, the technique includes: obtaining an electronic document in a binary format, reforming the electronic document in a markup language format using information selected from the binary format document according to predefined extraction parameters, and inserting an encoded version of the electronic document in the binary format into the electronic document in the markup language format. A markup language document can include a first and second portions, the first portion including a subset of information, including rules governing how the electronic document is processed by a machine, from a binary format document corresponding to the second portion, and the second portion including an encoded version of the binary format document, where the electronic document is fully transformable to the binary format after a modification to the electronic document in the markup language format.
