===== Checkpoint 3 (max 15 pts) =====

----
Deadline **2. 1. 2022**

==== Goal ====
Integrate data sets and answer the question using SPARQL query.

==== Deliverable ====

  * prove the interconnection of data by the sample integration of various knowledge among datasets with high number of mutually interlinked resource from all the data sets, delivered as **RDF file(s)** or as content of your **GraphDB repository**,
  * design non-trivial SPARQL queries over the datasets you create, showing the integration capabilities of the integrated datasets by answering the question given in the [[cp1|Checkpoint 1]] (include how long queries run, results and their interpretation),
  * and include them into the description (1-2 page extension of the report from [[cp2|Checkpoint 2]]). In the description also sum up the design decisions you made, the pros/cons of the ontology, description and evaluation of SPARQL queries 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.

For the integration ontology -- it may be beneficial to design the ontology into the multiple files and import them into one top level ontology.
