Developing appropriate models for systems, programming languages and processes is not easy.  Hence, several metamodels have been proposed. Metamodels are framework theories which provide general, structural results simplifying and driving the development of models of specific systems and languages. There are frameworks for operational semantics (such as GSOS, graph rewriting systems, Milner’s bigraphs, coalgebras), for denotational semantics (such as algebraic/bialgebraic specifications, monads, enriched Lawvere theories, mathematical operational semantics), and for logical semantics (such as metalanguages for deductive systems, i.e. Logical Frameworks). The boundaries between these metamodels are blurred, and techniques and ideas from one can be reapplied to the others. Moreover, metamodels can help in the definition of new computation and programming paradigms.

The goal of the MeMo workshop is to bring together researchers working on and with metamodels, with the aim to share insights, uncover similarities and differences, possibilities for cross-fertilization and stimulate further research in this exciting area.  We solicit contributions in the theory and applications of meta models: theoretical results, tool implementations, real-world applications, case studies, new application areas, integration of meta-models with programming languages, etc.  Topics include (but are not limited to):

  • Metamodels for operational semantics: bigraphical reactive systems, coalgebras, psi-calculus, SOS formats, term and graph transformation systems, tile models, ULTraS and FuTS, etc.
  • Metamodels for denotational semantics: algebraic/bialgebraic specifications, monads, enriched Lawvere theories, mathematical operational semantics, etc.
  • Metamodels for logical semantics: metalanguages for deductive systems, concurrent logical frameworks, etc.
  • Expressiveness issues of metamodels
  • Applications of meta-models to the design of computational paradigms (e.g., for agent-based and context-aware computing)
  • Tools, implementations, and experiments

Selection Procedure

Each paper will be peer-reviewed by at least three PC members. Evaluation criteria will be technical quality, readability, novelty and scope.


We invite three types of submissions:

  1. Full Papers;
  2. Tool presentations;
  3. Posters.

Full papers and tool presentations will appear in the pre-proceedings and post-proceedings and must report previously unpublished work and not be simultaneously submitted to other conferences/workshops with refereed proceedings. In addition, we invite poster announcements of already published results, should the authors be interested in discussing their published research with the MeMo community and giving a talk. Posters will not be part of the post-proceedings. Submissions must be made electronically in PDF format via EasyChair ( Full papers should not exceed 15 pages in length, while tool presentations and posters should not exceed 8 pages with the EPTCS style ( Accepted papers, tool presentations and posters must be presented at the workshop by one of the authors.

Post Proceedings Special Issue

A post-proceedings will be published as a special issue in the Journal of Logical and Algebraic Methods in Programming. Contributions to the Special Issue will be regularly peer-reviewed according to the standard journal policy, but they will be handled in a shorter time than regular submissions. See the call for papers for deadlines and submissions details.
