Construction of a language hierarchy
Source publication
Domain-Specific Languages (DSLs) allow modelling concerns at a high abstraction level. This simplifies the modelling process and ensures that non-technical stakeholders can be more closely involved in software development. However, in-creasing the abstraction level causes details of the problem domain to be excluded from the problem space. In some...

In order to be able to specialise metamodels and thereby enhance reusability of metamodels, we introduce the notions of metamodel types and subtypes. Model-driven engineering considers models and metamodels as first-class entities, however, there has not been much work on how to type models or metamodels. In this paper we discuss how a metamodel can be enclosed within a class and how this enclosing class defines the type for the metamodel. This allows us to use established object-oriented mechanisms on the metamodel level and supports specialisation of metamodels.
In model-driven engineering, models are considered first-class entities. Model-driven engineering has been around for over a decade. Still, there has not been much work on how to type models or metamodels, which is important to realise true model-driven software development. In this paper, we discuss how a metamodel can be typed by means of an enclosing class whose state can be utilised by tools such as editors and interpreters. This allows using established object-oriented mechanisms on the metamodel level and supports specialisation of metamodels. Copyright © 2014 SCITEPRESS - Science and Technology Publications.

CAC (context aware computing) has recently emerged as a new computing paradigm promising adaptable systems development. Context awareness for services oriented systems (SOS) raises many challenges. Particularly, the challenge of engineering such systems which consists of the definition of modeling approaches, processes, techniques and tools to facilitate construction of these systems. In this paper, we propose a generic metamodel for Adaptable, Domain Specific and Service Oriented Systems. Our metamodel aims to facilitate the creation of Domain Specific Language (DSL) for adaptable and service oriented architecture. For a specific domain the language developer must produce their specific service metamodel based on our generic service metamodel.
