Documentation
[TODO NICO] Ich glaube, die Grafik müssen wir in zweierlei Hinsicht anpassen: (Könntest du mir eine editierbare Version der Grafik schicken?) 1.) "Aware" ersetzen durch etwas generischeres wie "Context Provider" 2.) Der neue zentrale K/V-Store muss rein. Im zuge dessen, würde es sinn machen das mit dem Block "Configuration File" zusammen zu legen?
The general architecture of vStore and its interfaces can be seem in the above figure. The main components of the framework are:
- Context aggregator:
- Rules:
- Matching engine:
To make it all work, you need the following things besides an instance of the framework:
- Configuration:
- Storage nodes:
- Context providers:
