A meta-language for portfolio assessment

This paper examines accumulation methods for effective use of portfolios and develops a meta-language ("MelaPass") for describing the framework of portfolios for making a portfolio assessment. The purpose of MelaPass is to describe the structure of portfolios which have "soundness" and "exhaustiveness" features, and the language can be used in cooperation with existing metamodels (i.e., it has an "affinity" feature). The paper also develops a portfolio assessment support system called "passports" that is based on MelaPass. By using this system, users can design portfolio assessments based on MelaPass and use and manage portfolios.
