scope:

This part of ISO/IEC ISP 10607 (AFT22) covers access to files between the filestores of two end systems, using the OSI connection-mode Transport Service to provide the interconnection. One end system acts in the Initiator role and requests access to the file, the other end system acts in the Responder role and provides access to the file in the virtual filestore. Access of files is supported for files with an unstructured, flat or random access constraint set and containing binary or character data. This part of ISO/IEC ISP 10607 specifies implementations that support file transfer and file access, i.e. the ability to: a) read an FADU which is identified by node name, node number or by postion (depending on constraint set and document type), b) write (replace and/or extend and/or insert, depending on the constraint set and document type) to a file, and c) locate and erase within a file; and optionally to a) create and delete a file, and b) read the attributes of a file. Grouping of actions is not mandatory. Therefore, the above file actions can be performed separately and also, multiple file actions can be performed within a given regime.
