Many researches have achieved to reuse existent experience at each step of software life cycle. It is achieved various study about Design Pattern serving that abstract level solves design problem at high level. But, design step is not supplying design information that is abstracted so that new designers may reuse standardizing defined good design information. Therefore, in this paper, to do so that can reuse existent design information because composes Design Pattern can solve problem at design step, and extend design information that also is standardized XMI to base meta model of Design Pattern. And I did so that can compose Design Pattern utilizing MetaModel of Design Pattern standardized by XMI. Therefore, software designer can reuse composing existent design information that is could standardize problem at design because uses MetaData of standardized Design Pattern, and designs by Design Pattern base.
