# Spazio 2 protocols convention

A special convention must be followed when defining Virtual File Systems for Spazio 2 Local PR4 and PR5 Protocol Servers.

The Spazio 2 architecture is based on QManager/Queue paradigm and the configuration is done using local configuration files that control access to an existing Queue defined for a particular QManager.

In Spazio 2 architecture, files must belong only to the pre-defined set of a Queue.\
PRIMEUR Data One has a completely open architecture, so a file can belong to any Virtual File System defined.

To emulate the QManager/Queue paradigm, the VFS used by a PR4/PR5 local server must be organized as follows:

* VFS Name = Emulated Spazio 2 Node Name
* VFS = \<QManager Name>/\<Queue Name> (repeated for all QManager/Queues defined)
