The Model-Driven Engineering (mde) paradigm promotes the usage of conceptual models in information systems (is) engineering and research. As engineering products, conceptual models must have quality, which applies on both conceptual models and modeling language employed to build them. This paper presents a modeling language quality evaluation framework. This framework uses the principles from the popular Zachman framework for information systems as a taxonomic tool applied over modeling rtifacts used in an information system development. The purpose of this taxonomic tool is to perform analytic procedures that are aligned with an is reference architecture and ontological reasoning. Throughout this work, we describe how the Zachman framework supports analytics over modeling languages for quality purposes by its native management of semantics.
