Applications of OMA To give an example, we have a network of cultural institutions. They operate with their specific professional language and terms, like "coproduction", "artist", "partners", different areas in the field of art disciplins and so on. Another example would be a biological research institute. They deal with another language. By setting up a tree, covering the different models of communication, OMA gives a broad range to project users needs into this structure. Examples: webzines museums catalogue systems scientific institutions intranets of all kinds
