Ontology is a term in philosophy and its meaning is "theory of existence", and based on my understanding of ontological theories about nature and the types of things that lead to existence. Therefore, I chose to unlock information about the ontology related to art, because as we know around us, art is present and the beauty of life is colored by art. As we all know, art is not only a means of creating instances of a painting canvas for mere mortals, but it also has a meaning and a distinctive mode of existence. An ontology that deals with forms and modes of art and led to the creation of art. art. The work of art is also the result of a social contract which is not natural but human inventions. How we categorize them depends on our interests. Moreover, ontology is not easily separated by sociological and ideological nature as they are closely related to each other. Therefore, the number and classification of topics of interest can reveal why and how art is produced or created and should be appreciated. Here are some traditional art classifiers in terms of media such as words, sounds, paint and stone, etc. the species they are like sculptures, musical literature, theater, ballet, etc. In addition to style or content, they are like tragedy, comedy, surrealism, impressionism. Additionally, for some this may mean that translation leads to complex is difficult to understand and interpret, but it is an art that is meant to lead to deep meaning and full of art. The visual art of ontology can be seen as comparable to other artifacts of ontology's success. as a result of painting produced by a piece of material located above the canvas and covered with traces of paint. This analogy can also be described with a spoon made from a medium of paper...... sharpen and criticize art. In an attempt to discuss this concept, the ontology is descriptive and not prescriptive or entrepreneurial. In a sense to apply the distinction between singular arts and multiple arts. What do we mean by a unique work of art? A unique work of art is unique and only occurs in one place and at one time, such as painting, collage, carved sculpture, and Polaroids. What is meant by a multiple of works of art is that they have more than one instance where they are different but at the same time. If the evidence is seen above, it may be a little difficult for us to understand, but understanding is with the closest example of such a novel which has many copies, many film screenings and many printed photos. Each of the events is in some way and presentations.
