Architecture of XPPL
https://pzwiki.wdka.nl/mw-mediadesign/images/b/bc/Xppl_graph.svg
The main architecture of the XPPL
The Pi#1(Big Sistapi) contains the catalogue and the database (public), the scripts (web serving, indexing), the book files (local), the address book of the users. It is connected to the local network of PZI and communicates with the public server of PZI.
The server PZI contains only the catalogue, that has being copied from the Pi#1 with scp and it is updated automatically.
The catalogue is public and can be accessed through a url in the web (the fixed IP of the Pi#1).
Instances of XPPL (Mirroring)
This architecture can be duplicated in other networks.
!!Problems!!
- Local Network Pi problem
- public server writeable from many sources
