Overview
ISO 8571-1:1988/Amd 1:1992 is Amendment 1 to Part 1 (General Introduction) of the ISO standard series for File Transfer, Access and Management (FTAM) within the Open Systems Interconnection (OSI) framework. This amendment - titled Filestore Management - extends the general introduction with added definitions, filestore structure concepts, and clarifications on access, accounting, concurrency and attribute dynamics. It is published by ISO/IEC JTC 1 (Information technology).
Key topics and technical requirements
- Filestore terminology and structure: new and amended definitions for filestore concepts such as file, file-directory, reference, filestore tree/root, primary pathname and linkage/parenthood/childhood.
- Virtual Filestore (VFS) model: clarifies object types (files, file-directories, references), their mapping in a tree, and how pathnames are resolved to objects.
- Attribute model and dynamics: distinguishes persistent object attributes (descriptive, accounting, access rules) from activity attributes (session-specific values established during FTAM regimes) and explains how attribute state is communicated between initiator and responder.
- Access control: specifies dual sources of access control - the target object’s access control attribute and path-access-control attributes on intermediate file-directories/references. Access checks are required for selection/open regimes and are performed against each access control list in the pathname.
- Concurrency control: defines mechanisms only for file object access, intended to provide a consistent view for initiators by restricting concurrent access where necessary.
- Accounting and charging: FTAM supports association of account names and charging parameters with objects and regimes; nested regimes can override account assignment for finer-grained charging.
- Amendment structure: introduces additional subclauses and figures (notably subclauses 5.8, 11.3.2/11.3.3, A.6 and new figures) that will be renumbered in subsequent editions.
Practical applications and target users
Who benefits:
- Protocol implementers and vendors building FTAM-compliant file transfer/access/management systems
- Systems architects and integrators designing interoperable filestores in OSI environments
- IT managers, security architects and auditors responsible for access control policies and accounting in distributed file environments
- Test labs and conformance assessors validating FTAM protocol and filestore behavior
Typical uses:
- Designing filestore structures with clear parenthood/linkage semantics and pathname resolution
- Implementing robust access control and concurrency mechanisms for shared files
- Enabling cross-vendor interoperability for file transfer and remote file access in OSI stacks
- Applying accounting and charging models tied to file operations and regimes
