Docker: Service types

Our framework separates services into three broad categories:

1. Data sources - usually triplestores or convential databases
2. Agents - which might do any or all of:
   • retrieve input from one or more data sources
   • perform operations on data
   • write output to one or more data sources
   • provide an API
3. Web applications
   • e.g. visualisations that present data retrieved from agents
   • may include interactive elements that can request data updates/manipulation from agents

Communication between services is usually in the form of HTTP requests or SPARQL queries.
