Meta-models play a pivotal role in Model-Driven Engineering (MDE). They are used to create domain-specific models, and to type model management operations like model transformations or code generators. However, even though creating meta-models is a common activity, it is currently mostly a manual activity, which does not profit from existing knowledge. In order to facilitate the meta-modelling task,...
In this paper we present a model transformation language based on logic programming. The language, called PTL (Prolog based Transformation Language), can be considered as a hybrid language in which ATL (Atlas Transformation Language)-style rules are combined with logic rules for defining transformations. ATL-style rules are used to define mappings from source models to target models while logic rules...
The Data-as-a-Service (DaaS, or Data Services) paradigm enables an on-demand, service-based access to data, relying on similar principles to Software-as-a-Service (SaaS). DaaS permits centralized data quality management, a uniform view and access to heterogeneous data, and enables exposing a richer, domain-specific data model to users. Within this context, we are witnessing a trend in institutions...
