Revealing and being able to manipulate the structured content of PDF documents is a difficult task, requiring pre-processing and reverse engineering techniques. In this paper, we present OCD, an optimized, easy-to-process and canonical format for representing structured electronic documents. The system and methods used for reverse engineering PDF documents into the OCD format are presented as well as the techniques to optimize it. We finally expose concrete evaluations of our OCD format compactness and restructuring performances.
