The following section shows four competency questions which served first to define scope of the CEO/CAMO ontologies. They are also useful for validating if the created onotlogies work properly. The four questions are converted to the SPARQL query language. The query is then fired to the LD-CE triplestore endpoint and results can be seen below in table or map format.
