“…In the literature, three main storage strategies can be distinguished to manage ontology versions (Fernández, Polleres, & Fern, ). - Independent copies (IC) approach (Heflin & Hendler, ; Klein, Fensel, Kiryakov, & Ognyanov, ; Kondylakis & Plexousakis, ; Pittet, Cruz, & Nicolle, ; Sassi, Jaziri, & Alharbi, ; Völkel & Groza, ) is a naïve storage strategy as it consists in just storing complete ontology versions in separate OWL or XML files (see Figure ). This policy offers complete and separate views of the domain states across different time periods.
