Covers management of files between the filestores of two end systems, using the OSI connection-mode transport service to provide the interconnection. Specifies implementations that support file management, i.e. the ability to (a) create and delete a file, and (b) read and change the attributes of a file. Specifies only that functionality which is additional to the functionality of the related parts. Specifies how the OSI FTAM application standard shall be used to provide the functions defined above. The requirements placed on an implementation in this part of ISO/IEC ISP 10607 are solely those necessary for operation of the protocol specified. Describes the actions and attributes of the virtual filestore, and the service provided by the file service provider to file service users, together with the necessary communications between the initiator and the responder. Applicable on the double lines of figure 1. The mapping between the virtual filestore and the real filestore together with the local data management system is not defined in this part of ISO/IEC ISP 10607.
