Data

Data is under development, so subject to change (quite much hopefully).
Nodes interact with Data according to a protocol. We suggest we comply with the AMQP standard. https://www.amqp.org

Guiding principles

• Precedence Analysis
• Desired state is assumend
• Data holds the Universal Truth

Data presents nodes on request with node taylored views on the Universal Truth, thus supplying the nodes with the the information they require. This is the normal situation in which Data provides updates on the views. Data may respond that it needs additional information. Nodes may find Data needs to be updated with information they hold.

Feeds

Nodes send out feeds on request. This request is triggered by a Data response to an information request. The node assumes the requested information to be available from Data, but Data can decide to ask for more information before being able to supply the requested information.
