Ontology have become a relevant representation formalism and many application domains are considering adopting them. This attention claims for methods for reusing domain knowledge resources in the development of domain ontologies. Accordingly, in this paper we discuss a general methodology to create domain ontology for more than one object oriented language (OOP) like Java, PHP and C++. A lot of software development methods specially Web applications have presented most of these methods that are focusing on the structure of distributed systems and security, in which they are connected through networks and the internet; resulting in more valuable business and critical assets stored, searched and manipulated by World Wide Web. The aims of this study building domain ontology for OOP language classes for different OOP languages or different versions of the same language is an exciting opportunity for researchers to access the information required under the constant increase in the volume of information disseminated on the Internet. By creating Ontology domain for OOP, we can Improve methods of viewing and organizing information, improve the way of processing, in addition to increasing the vocabulary and their relationship to terminology as well as the rules used in natural language with OOP languages. The clear identification of the properties and relations of terms is the starting point to become Ontology domain. The importance of the domain Ontology among object oriented programming languages is that through the synthesis of these relationships or Ontology an OOP can be achieved through web by any junior programmers.
