In recent years, a wide range of tools and methodologies have been introduced in the field of multi-level meta-modeling. One of the newest approaches is the Dynamic Multi-Layer Algebra (DMLA). DMLA incorporates a fully self-modeled textual operation language (DMLAScript) over its tuple-based model entity representation. This textual language provides effective and complex features when editing models. On the other hand, the language supports the precise injective mapping of the multi-layers. However, such complexity comes at a price. Using DMLAScript can be difficult in practice for users who are only familiar with the classical, object-oriented way of thinking, and are not confident with the multi-level approach. In this paper, we introduce the concepts of a new language above DMLAScript, which supports the more effective manipulation of concrete domain models by taking advantage of the particular process of multi-level modeling within DMLA. Although the approach is technically bound to DMLA, the concepts discussed in the paper are of general use.
