Raster Document Object
The .RDO (Raster Document Object) file format is the native format used by Xerox's DocuTech range of hardware and software, that underpins the company's "Xerox Document On Demand" "XDOD" systems. It is therefore a significant file format for the "print on demand" market sector, along with PostScript and PDF. RDO is a metafile format based on the Open Document Architecture (ODA) specifications: In Xerox's RDO implementation, description and control information is stored within the RDO file, while raster images are stored separately, usually in a separate folder, as TIFF files. The RDO file dictates which bitmap images will be used on each page of a document, and where they will be placed. Features and disadvantages This approach has advantages and disadvantages over the monolithic approach used by PDF: The disadvantages of RDO are that it is a largely proprietary format, and the multi-file approach means that file management and orphan control is more of an issue: one cannot tell ...

Native And Foreign Format
A native format, in the context of software applications, refers to the file format which the application is designed to work with. It captures the internal reality of the program as well as is possible. Most likely this is also the default format of the application. A native file format therefore most likely has a one to one relationship with the applications features. In turn, a foreign format is not a true reflection of application internals, even though it may be supported by an application. To read a foreign file causes translation of data, this can cause data loss and further editing may prevent faithful writing back to the foreign format. Example A document writer application may support a multitude of files, ranging from simple text files that only store characters and not font faces or sizes, to complex documents containing text effects and images. However, when these text files or documents are opened, they are not necessarily edited in their original format. Instead, th ...
