ISO 8571-2:1988

Extends the definitions given in ISO 8571 part 2 for an abstract model of the virtual filestore for describing files and filestores, sets of actions that may be used to manipulate the elements of this model, and the properties of individual files and associations to incorporate the concepts of overlapped access. The objective in introducing overlapped access is to allow more efficient access to structured files when a single initiator has a need to perform many reading and updating operations.
