Practical Multi-level Modeling on MOF-compliant Modeling Frameworks

This paper describes practices for multi-level modeling by only using existing modeling frameworks that comply Meta-Object Facility (MOF). We design modeling patterns for achieving the multi-level modeling methodologies on Eclipse Modeling Framework, and implement the dataflow model by applying the patterns. Moreover, we attempt to compare the patterns regarding the facilitation of developing both our tool and plugins. We found Orthogonal Classification Architecture (OCA) pattern is easier to develop our tool than powertypes pattern, but regarding plugins for our tool, powertypes pattern can define modelto-text transformation templates more simply than OCA pattern.
