In general, a property can be set for one or more classes. In this way, they can be restricted for only parts of the ontology. A property gets an value (e.g. a data type) if it is set for an instance. Values can have different data types, e.g. string or boolean values. A property can show a semantical role between two instances so that cross links can be created. It can be also set for additional information.
In this ontology properties represent a special information level. This level is divided into an annotation part (information of a annotator, etc.), a commentary part (information of a narrator, additional information of a literary character) and a part for general information (like a storytitle, an author, etc.).
