2. At the end of today… …you will know about … you will be able to
foundations of ontology engineering and usage
ontology lifecycle activities
the NeOn Toolkit
… you will be able to
use the NeOn Toolkit for complex ontology engineering tasks
develop your own plugins for the NeOn Toolkit

“Shaping the future infrastructures for semantic applications”
EU IST Integrated Project
Start date: March 2006
Duration: 4 year project
Funding: € 10M (FP6)
Key outcomes from NeOn
Open, scalable and service-centered reference architecture for supporting the lifecycle of semantic applications
The NeOn Toolkit – a resource for engineering contextualized networked ontologies and semantic applications
Industry-strength documentation and reference material
Three case studies in two sectors: pharmaceuticals and agriculture/fisheries

5. What is the NeOn Toolkit?
Reference implementation of the NeOn architecture
Support ontology engineering and management
Support for complete ontology lifecycle
Support for different languages (OWL, F-Logic)
Support for networked ontologies (modules, mappings)
Built on the Eclipse platform
Extensible architecture
Via Eclipse plugin mechanism
Via Web Services
- Management of mappings, modules
