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:
- Notation: the representation of a modelling construct (e.g. graphical)
- Syntax: the specification of a modelling construct
- 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:
- Classes and Relations: as the base modelling constructs for every modelling toolkit
- Attributes on Instance and Class Level: to provide means to specify instance objects or define classes accordingly.
- Special Attributes on Instance and Class Level: to enable ADOxx specific functionality, such as attribute-dependent graphical notation.
- Attribute facets: configuration of attribute appearance and behaviour
- Modeltypes and model type attributes: similiar as for classes and relations on the model type level.
