| 5 | is a object-oriented language for model construction based on CommonLispObjectSystem and the |
| 6 | MetaObjectProtocol. |
| 7 | |
| 8 | It uses the facilities of CommonLisp to dynamically handle ClassMetaObjects and allow changes and |
| 9 | editing. Fdl defines a macro language for generic class definitions as well as an ApplicationProgramInterface to access FdlClass definitions and their parts (FdlEffectiveSlotDefinition). |
| 10 | The access methods allow addition, deletion and manipulation of classes and slots. |
| 11 | |
| 12 | FdlClass es are instantiated as FdlObjects, which implies that all of their parts are also automatically |
| 13 | instantiated and initialized. It is possible to store ParameterSets with classes that override the default |
| 14 | values for parts of a class. |
