Implementation benefits ISO 19109 describes a metamodel framework for the definition of features and application schemas. An application schema defines a formal description of the data structure and specifies the associated operators for manipulating and processing data by an application. Application schemas are important for data and application interoperability. ISO 19109 also defines the General Feature Model (GFM), which is a model of the concepts required to classify a view of the real world. The main concepts of GFM are: name, description, feature type, feature attribute, feature associated roles characterizing the feature type, and the defined behaviours of the feature type.
