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, 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 the model type level.
