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 from a computer's file system whether all the files required for a document to print are present and correct.
In RDO's favor, the multi-file approach allows a networked device to load the small RDO file and then request the larger bitmap files only when necessary: This allows a full job specification to be loaded and installed over a network almost immediately, with the larger bitmap files only having to be transferred as and when needed, allowing more flexibility for managing network traffic loading.
The TIFF file format is highly portable, and Xerox's MakeReady software, supplied with its XDOD systems, readily imports and export postscript files: however, the Xerox "on demand" systems typically require a document library to be stored as RDO / TIFF files, and most non-Xerox applications will not read RDO structures directly.

Famous quotes containing the word features:
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
