The availability of shared software models provides opportunities for reusing, adapting and learning from them. Public models are typically stored in a variety of locations, including model repositories, regular source code repositories, web pages, etc. To profit from them developers need effective search mechanisms to locate the models relevant for their tasks. However, to date, there has been little success in creating a generic and efficient search engine specially tailored to the modellingarXiv:2008.11858v1 fatcat:emnd7g3ks5fchl7tpl6xtawtam

MAR uses a query-by-example approach, that is, it uses example models as queries. The search takes the model structure into account using the notion of bag of paths, which encodes the structure of a model using paths between model elements and is a representation amenable for indexing. MAR is built over HBase using a specific design to deal with large repositories. Our benchmarks show that the engine is efficient and has fast response times in most cases. We have also evaluated the precision of the search engine by creating model mutants which simulate user queries. A REST API is available to perform queries and an Eclipse plug-in allows end users to connect to the search engine from model editors. We have currently indexed more than 50.000 models of different kinds, including Ecore meta-models, BPMN diagrams and UML models. MAR is available at http://mar-search.org.
Businesses are more and more modernizing the legacy systems they developed with Rapid Application Development (RAD), so that they can benefit from the new platforms and technologies. In these systems, the Graphical User Interface (GUI) layout is implicitly given by the position of the GUI elements (i.e. coordinates). However, taking advantage of current features of GUI technologies often requires an explicit, high-level layout model. We propose a Model-Driven Engineering process to performdoi:10.1007/s10515-013-0130-2 fatcat:p3p2tonw5ndwbesprypfmeidha

Based on the information we obtain, other reengineering activities can be performed, for example, to adapt the GUI for mobile device screens.

Writing navigation expressions is an important part of the task of developing a model transformation denition. When navigation is complex and the size of source models is signicant, performance issues cannot be neglected. Model transformation languages often implement some variants of OCL as their navigation language. Writing ecient code in OCL is usually a dicult task because of the nature of the language and the lack of optimizing OCL compilers. Moreover, optimizations generally reducedoi:10.1007/978-3-642-02408-5_16 fatcat:lbuf2a2dyfcivkgr7qgh3fkwuq

We propose to complement the regular navigation language of model transformation languages with a high-level navigation language, in order to improve both performance and readability. This paper reports on the initial results of our experiments creating the HLN language: a declarative high-level navigation language. We will motivate the problem, and will we describe the language as well as the main design guidelines.

P r e l i m i n a r y V e r s i o n P r e l i m i n a r y V e r s i o n Abstract. Model transformation is a key technology of model driven software development approaches. Several transformation languages have appeared in the last few years, but more research is still needed for an in-depth understanding of the nature of model transformations and to discover desirable features of transformation languages. Research interest is primarily focused on experimentation with languages by writingdoi:10.1007/11880240_24 fatcat:6xig5o7lfzbcvizfxm7tcqzge4

RubyTL is a hybrid transformation language defined as a Ruby internal domain specific language, and is designed as an extensible language: a plugin mechanism allows new features to be added to core features. In this paper, we describe this plugin mechanism, devised to facilitate the experimentation with possible features of RubyTL. Through an example, we show how to add a new language feature, specifically we will develop a plugin to organize a transformation in several phases. Finally, we discuss the advantages of this extensible language design.
Applying Model-Driven Engineering (MDE) in industrial-scale systems requires managing complex models which may be very large. These models must be persisted in a way that allows their manipulation by client applications without fully loading them. In this paper we propose Morsa, a model repository that provides scalable manipulation of large models through load on demand and incremental store; model persistence is supported by a NoSQL database. We discuss some load on demand and incrementaldoi:10.1007/s10270-013-0326-8 fatcat:dinmxxev2fel3hsy4vodjo5v7y

A prototype that integrates transparently with EMF is presented and its evaluation demonstrates that it is capable of fully managing large models with a limited amount of memory. Moreover, a set of benchmarks has been executed, exhibiting better performance than the EMF XMI filebased persistence and the most widely used model repository, CDO.

El acceso a la versión del editor puede requerir la suscripción del recurso Access to the published version may require subscription Abstract Model-Driven Engineering proposes the use of models to describe the relevant aspects of the system to be built and synthesize the final application from them. Models are normally described using Domain-Specific Modelling Languages (DSMLs), which provide primitives and constructs of the domain. Still, the increasing complexity of systems has raised thedoi:10.1016/j.is.2013.06.001 fatcat:jqtl6powe5fbrcupkb7j3xv67u

The problem is that developing such abstractions for each DSML from scratch is time and resource consuming. In this paper, our goal is reducing the effort to provide modelling languages with abstraction mechanisms. For this purpose, we have devised some techniques, based on generic programming and domain-specific meta-modelling, to define generic abstraction operations that can be reused over families of modelling languages sharing certain characteristics. Abstractions can make use of clustering algorithms as similarity criteria for model elements. These algorithms can be made generic as well, and customised for particular languages by means of annotation models. As a result, we have developed a catalogue of reusable abstractions using the proposed techniques, together with a working implementation in the MetaDepth multi-level meta-modelling tool. Our techniques and prototypes demonstrate that it is feasible to build reusable and adaptable abstractions, so that similar abstractions need not be developed from scratch, and their integration in new or existing modelling languages is less costly.
The intensive use of models in Model-Driven Engineering (MDE) raises the need to develop meta-models with different aims, like the construction of textual and visual modelling languages and the specification of source and target ends of model-to-model transformations. While domain experts have the knowledge about the concepts of the domain, they usually lack the skills to build meta-models. Moreover, meta-models typically need to be tailored according to their future usage and specificdoi:10.1007/s10270-013-0392-y fatcat:li5o7bz4jbdp3bxjahcelltkvy

These issues hinder a wider adoption of MDE both by domain experts and software engineers. In order to alleviate this situation, we propose an interactive, iterative approach to meta-model construction enabling the specification of example model fragments by domain experts, with the possibility of using informal drawing tools like Dia or yED. These fragments can be annotated with hints about the intention or needs for certain elements. A meta-model is then automatically induced, which can be refactored in an interactive way, and then compiled into an implementation metamodel using profiles and patterns for different platforms and purposes. Our approach includes the use of a virtual assistant, which provides suggestions for improving the meta-model based on well-known refactorings, and a validation mode, enabling the validation of the meta-model by means of examples.
