Abstract: Twolayer modeling method based on ModelView Controller pattern is proposed in detail. The modeling system is developed by Model Driven Architecture, meets the needs of Metaobject Facility standard, extends Unified Modeling Language, and supports the technique of Aspectoriented modeling. So the difficult problem about requisite languages of different aspects and abstract layers of every system in modeling field can be resolved. By means of this modeling method, field metamodels and filed language can be upbuilt in the metamodeling phase.

Key words: modelviewcontroller, model driven architecture, metaobject facility, aspect oriented
