Based on the given datasets, an ontology should be engineered, the data shall be integrated in a knowledge graph as well as the business questions should be answered from that graph.

Objectives

A company want to make their knowledge graph accessible via a SPARQL service.

The SPARQL service need to answer business questions, examples:

1. Find related products (e.g. cluster by packaging size or weight)
2. Find services / products without a product manager
3. Find services / products without responsible department
4. Identify alternative experts that can take over responsibility

Three datasets exists and these data have to be reusable in a knowledge graph accessible via a SPARQL service.

A XML file of an organisational structure of the client:

    <dept id="1" name="Engineering">
        <manager>
            <email>A.B@company.org</email>
