3.3 Communication model

The following specifications use the MERISE conception method. Here are the typographical conventions used:

• Caps are use for ACTORs and ACTIVITIEs,
• Bold is use for processings,
• “<>” are use for object’s <states>,
• Verbatim is used for events, which may be:
  • # command : ADMIN or DATE command line
  • $ command : PUBLISHER command line
  • (message) : final message like mail and motd
  • <message> : synchronous message using a socket
  • [register] : asynchronous message using signal
  • function() : internal call

Communication model:

• 4 actors interact with the MEDIATEX activity
  • - USER (see Who)
  • - PUBLISHER (see Who)
  • - ADMIN (see Who)
  • - DATE (see Who)
• Events in
