Description

R-IOSEMIT enables you to simulate a predefined set of data called events. An event has to follow a predefined structure and a topic. In R-IOSuite three types of sensors can be simulated: the events emitted from webservices, from tweets or from the Maple location tags.

How does the interpretation work?

R-IOSEMIT enables R-IOSUITE to interpret events in real-time. It uses a Complex Event Processing (CEP) engine to apply the interpretation rules available in your Use-Case (at src/main/resources/webjars/gind/usecases/loireflooding/interpretation-rules.

R-IORED will be design to update these rules through a dedicated tool.

The first event is notified to the CEP engine by the notify() method of the CEP rules manager
The second event is notified to the CEP engine etc.
...
When an event fulfills the conditions of an interpretation rule, the High level interpretation engine notifies that a node or a edge has to be deleted/updated or added to the ACTIVE WORLD (stored in Neo4J). This action is stated in the interpretation rule.
Then, the interpretation manager uses the notification to update the ACTIVE WORLD with the interpret() method.

Concept of Data Source

Last update: 02 Apr 2019

Type: Data Source

Extends: SemanticConcept

Category: Context

Origin: Native/Dedicated

Protocol: WSN/Twitter/Mapple

Type: SIMULATED/REAL

Simulated Data Source

Files (.xml) to be linked to a simulated WSN data source:

Illustration: Loire Flooding

Topic Set Producer - Topics corresponding to the events to be simulated
Sensors Event Topic Namespace - List of topics available
Event - file with the events to be simulated
Configuration - file with the configuration of the simulation: the frequency of the simulation and the configuration of the graph to be fed (on the interface during the simulation)

Files (.xml) to be linked to a simulated Mapple data source:

Illustration: HelloDiag

Event - file with the events to be simulated
Configuration - file with the configuration of the simulation, especially to configure the graph to be fed (on the interface during the simulation)

Structure of the configuration file

<datasetConfiguration>:

<emissions>: <frequency> (n <time>) OR <period>
<chartConfig>:
- <title>
- <lineChart> OR <map>

<lineChart>:

<eventType>
<axisX (1 fois)> : <title>
AND <mappingEventElement>
<axisY (n fois)> : <title>
AND <mappingEventElement>
AND <color (hexa)>
AND <referenceLine> (<name> AND <value>)
<preview (boolean)>

<map>: <mapEvent> :

<eventType>
<latitudeMappingEventElement>
<longitudeMappingEventElement>
<preview (boolean)>
<polyline>: <color (hexa)>

How to configure interpretation engines ?

R-IO Suite allows to define rules in order to consider and interpret incoming events. There are 2 ways to configure this interpretation.

We can either use a CEP or a ML mechanism. Both interpretations are configured with the same configuration schema (see following).
