## Checkpoint 2 (max 25 pts)

### Goal

Design an integration ontology for the datasets from Checkpoint 1 and test it.

### Deliverable

• an ontology O extending the OSW ontology, delivered as OWL file(s),
• at least 100 mutually interlinked resources from all the datasets you selected in Checkpoint 0 and elaborated in Checkpoint 1, described by O, published in your GraphDB repository
• design of at least 3 non-trivial interesting SPARQL queries over the datasets you create, showing the integration capabilities of the integrated datasets,
• a short description (1-2 page extension of the report from Checkpoint 1) describing the design decisions you made, the pros/cons of the ontology and conclusion you make out of the semestral work.

### Details

Using the principles of ontological engineering and basing it on the Unified Foundational Ontology. Show how the ontology integrates the datasets on interesting non-trivial SPARQL queries over an OWL/RDF representation of the integrated datasets.
