Hello Benedikt, You may try to use a data integration approach before map the ontology with the data sources. For instance, you could to create a relational database in MySQL or other RDBM that you prefer. For this, you can try an ETL process using Pentaho Data Integration Tool[1]. If you have a relational database, the process of mapping the ontology is much more easy.
