These languages, coined domain-specific modeling languages (DSMLs), are essential components of model-driven architecture (MDA), platform-based design, and model-integrated computing (MIC). As a result, tools and methods for DSMLs have blossomed: Key research includes the heterogeneous composition of DSMLs, model transformations between DSMLs, approximations of formal properties within DSMLs, and reuse of DSML semantics.<\/p>\n<p>Despite this success, some key foundational issues concerning DSMLs have not been addressed. My presentation will address one of these issues; the structural semantics of DSMLs. The structural semantics of some DSML describes the set of structurally well-formed models that belong to that language. I will describe a formalization of structural semantics that takes into account current metamodeling techniques, provides a formal understanding of metacircularity, and allows us to algorithmically decide if two metamodels are equivalent. I will also describe how this theory has been used to provide a formal underpinning for existing metaprogrammable tools, providing proof-theoretic methods for evaluating DSML properties.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Model-based design encourages architects to use customized architectural languages that precisely target their problem domains.
