Generating instance models from meta models

Karsten Ehrig, Jochen Malte Küster, Gabriele Taentzer
2008 Journal of Software and Systems Modeling  
In this paper, we introduce instance-generating graph grammars for creating instances of meta models, thereby overcoming the main deficit of the meta modeling approach for defining languages.  ...  Despite several advantages of meta modeling such as ease of use, the meta modeling approach has one disadvantage: It is not constructive i. e. it does not offer a direct means of generating instances of  ...  Automatic derivation of instances from meta models is a complex task which needs tool support.  ...

instances as well as the inheritance of semantic dependencies in meta-modeling hierarchies in general.  ...  In particular, orthogonal meta-modeling enables the grouping of models on the same conventional meta-modeling layer based on additional semantic dependencies.  ...  In general, a model on layer S1 is called semantic instance of a semantic meta-model on layer S0. A semantic instance inherits information from its semantic meta-model.  ...

On the Generalization of Neural Combinatorial Optimization Heuristics [article]

Sahil Manchanda, Sofia Michel, Darko Drakulic, Jean-Marc Andreoli
2022 arXiv   pre-print
Through extensive experiments, on two CO problems, using both synthetic and realistic instances, we show that our proposed meta-learning approach significantly improves the generalization of two state-of-the-art  ...  Instead, we formalize solving a CO problem over a given instance distribution as a separate learning task and investigate meta-learning techniques to learn a model on a variety of tasks, in order to optimize  ...  GCN) model trained with instances coming equiprobably from the training tasks.  ...

Instantiation of Meta-models Constrained with OCL - A CSP Approach
english

Adel Ferdjoukh, Anne-Elisabeth Baert, Eric Bourreau, Annie Chateau, Remi Coletta, Clémentine Nebut
2015 Proceedings of the 3rd International Conference on Model-Driven Engineering and Software Development  
After the translation of a meta-model into a CSP, our software generates models that conform to this metamodel, using a Constraint Solver.  ...  The automated generation of models that conform to a given meta-model is an important challenge in Model Driven Engineering, as well for model transformation testing, as for designing and exploring new  ...  Experiments of model generation from several meta-models taken from the literature validate our modelling. We also experiment the assistance to a meta-model designer in a real use case.  ...

An executable meta model for re-engineering of database schemas [chapter]

Manfred A. Jeusfeld, Uwe A. Johnen
1994 Lecture Notes in Computer Science  
The rst part maps the input schema into a so-called meta model. The second part rearranges the intermediate representation, and the last part produces the schema in the target data model.  ...  Upcoming new data models and the necessity of seamless integration of databases into application programs require a cost-e ective method for mapping from one data model into the other.  ...  We w ould like to thank Matthias Hallmann and Wolf Fischer from CAP debis SSP for helping us to evaluate our prototype within a commercial system.  ...
