The architecture is shown here, where also some use cases I believe it
shall support are mentioned.
https://github.com/MEAE-GOT/W3C_VehicleSignalInterfaceImpl/tree/master/server/service_mgr

To test it requires some preparations, I followed my own checklist below
when I tested it.
Swedish is not that hard, you just go at it like the Swedish chef (
https://en.wikipedia.org/wiki/Swedish_Chef;).
The request to use is found in this file
https://github.com/MEAE-GOT/W3C_VehicleSignalInterfaceImpl/blob/master/client/client-1.0/Javascript/appclient_commands.txt


Se till att statestorage.db finns i service-mgr katalog
(Se till att statestorage-mgr executable finns i service-mgr katalog.)
Använd "DB browsr for SQLite" istället
Använd statestorage-mgr för att skriva in ett värde i DB för signal som ska
testas. (DB browser)
Starta VISS server.
Använd history control mgr för att initiera sparande av signal data:
create: bufsize:25 ; start: path-till-signal, freq:120  // 2 captures per
minut
Använd statestorage-mgr för att skriva in ett nytt värde i DB för signal
som ska testas. kolla service-mgr logg om det läses in. I så fall, skriv in
nytt. Upprepa 5ggr.
Skicka klient request för historisk data för denna signalen.

path":"Vehicle.Acceleration.Longitudinal
bufsize:25
freq:120
