Method and apparatus for managing document data for eventual presentation to a user

A management method and management system for physically managing data that represents an image for eventual presentation to a user, based on the data, wherein the data is first acquired from an appropriate image source in a source representation, next, the data in source representation is selectively converted to data in destination representation, using the selective storing of managed data as an intermediate item. First quantitative physical storage constraints associated with storing are assessed; second, quantitative physical converting constraints associated with converting the stored managed information from the source version information to the presentation version information is assessed, the converting being executed before the storing, and/or after the storing, on a dynamic trade-off basis between the first and second assessing; third, quantitative physical transfer constraints associated with transferring the managed information over a transfer facility are assessed, with the execution having a further dynamic trade-off basis through using the third assessment.
