The conversion of the higher education and literature ontology into RelOntoUML

In this article, I will transform an ontology representing higher education and an ontology representing a library into the RelOntoUML model. RelOntoUML modeling is a modeling created from a combination of relational model, ontology, and UML modeling. The relational model is used for database storage. The data is stored in relations. Ontology is a tool for knowledge representation. The ontology describes the elements of a topic. The UML model visually represents the elements of a topic. One of the disadvantages of the ontology model is that software developers are not familiar with it, but UML diagrams and the relational model are well known. The two models (CollageMngtSys, Literature) that will be presented and converted can be downloaded from the gihub in OWL format, and are open source. In this article, after introducing the ontology, relational model, and UML, these two systems are introduced and converted.
