# Modules

The main window of OntoGuiWeb is a **Control Panel** that can manage (networks of) ontology modules. The [**Control Panel**](/vlft/tools/ontoguiweb/modules/control-panel.md) also gives access to specific **tools**.

**OWL Tools** are generic tools to manage and visualize OWL ontologies: 

* [**SPARQL**](/vlft/tools/ontoguiweb/modules/sparql.md)
* [**Graphs OWL**](/vlft/tools/ontoguiweb/modules/graphs-owl.md)

**Engineering Tools** are dedicated to engineering tasks:

* [**Utilities**](/vlft/tools/ontoguiweb/modules/utilities.md)
* [**Asset Design**](/vlft/tools/ontoguiweb/modules/asset-design.md)
* [**System Design**](/vlft/tools/ontoguiweb/modules/system-design.md)
* [**System Control**](/vlft/tools/ontoguiweb/modules/system-control.md)
* [**Performance Evaluation**](/vlft/tools/ontoguiweb/modules/performance-evaluation.md)
* [**MQTT Sync**](/vlft/tools/ontoguiweb/modules/mqtt-sync.md)
* [**Virtual Environment**](/vlft/tools/ontoguiweb/modules/virtual-environment.md)
* [**Graphs Eng**](/vlft/tools/ontoguiweb/modules/graphs-eng.md)
* [**StateChart**](/vlft/tools/ontoguiweb/modules/statechart.md)
