This ECMA Virtual File Protocol Standard:
- defines a virtual file model (see section 2),
- defines operations on the virtual file model as abstract interactions between two virtual file service users, via the virtual file service (see section 3),
- defines the protocol to support the above service and its mapping into the underlying presentation service (see section 4),
- specifies the requirements for conformance with this protocol (see section 5).
The standard defines only what is needed for a basic file transfer. It provides the consistent technical basis for further virtual file protocol standards with extended scope.
The standard defines what is needed for compatible interconnection between information processing systems. It does not define local interactions between a virtual file service user and the virtual file service. It in no way defines interlayer interfaces.
This Standard is for the application layer of Open Systems Interconnection (see ISO 7498).
