Modelling Language Implementation on ADOxx

In this section we focus on the implementation of the model structure/modelling language in ADOxx. As a starting point the specification and definition of a modelling method as defined in [Karagiannis2002] is used to set the modelling language in context with the modelling procedure and mechanisms and algorithms resulting in a modelling method. In the following subsections we focus on the modelling technique, more precisely on the modelling language consisting of:

  1. Notation: the representation of a modelling construct (e.g. graphical)
  2. Syntax: the specification of a modelling construct
  3. Semantic: the definition of the meaning for a modelling construct

A modelling construct can be a (concrete) class, relation class, modeltype or attribute.

Generic Modelling Method Framework

Peforming a further drill-down into the modelling language, the following concepts are of interest from an implementation perspective:

  1. Classes and Relations: as the base modelling constructs for every modelling toolkit
  2. Attributes on Instance and Class Level: to provide means to specify instance objects or define classes accordingly. 
  3. Special Attributes on Instance and Class Level: to enable ADOxx specific functionality such as attribute-dependent graphical notation.
  4. Attribute facets: configuration of attribute appearance and behaviour
  5. Modeltypes and model type attributes: similiar as for classes and relations on modeltype level.
