+ <h2>Problem Definition</h2>
+ <p>
+ Suppose that we want to store the statement "Hasan is an Apache Clerezza user" in an RDF Graph. We can rephrase the statement to be more precise to "There is someone having the first name Hasan, who is an Apache Clerezza user". This statement can be represented in <a href="https://www.w3.org/TR/turtle/">Turtle</a>, assuming the use of an example ontology, as follows.

+ <div xmlns="http://www.w3.org/1999/xhtml" class="tx-blockcode">
+@prefix ex: <http://clerezza.apache.org/2017/01/example#> .
+_:a ex:hasFirstName "hasan" .
+_:a ex:isA ex:ClerezzaUser .
+ </div>
+ <p>
+ We are looking for a solution using the Apache Clerezza API to store in memory the two triples in a graph.
+ </p>
+ <h2>Solution</h2>
+ <p>The solution below uses the following Apache Clerezza libraries:</p>
