A conceptual schema language provides the semantic and syntactic elements used to describe the conceptual model rigorously in order to convey meaning consistently. ? A conceptual model described using a conceptual schema language is called a conceptual schema.

The approach to conceptual modelling in the ISO 19100 series is based on the Open Distributed Processing (ODP) Reference Model and the principles described in the Conceptual Schema Modelling Facilities (CSMF). Conceptual modelling 樂(lè)鵬， LIESMARS， Wuhan University ? a highlevel representation and description of the structure and content of geographic information ? the scope of the standardization addressed by the ISO 19100 geographic information series ? identifies the major aspects of geographic information that will be the subject of standardization activity ? standardize ? Structure of geographic information in data models and definition of operations ? Administration of geographic information ? The General feature model defines a metamodel for features and their properties. Domain reference model 樂(lè)鵬， LIESMARS， Wuhan University ? describes the general types of services that will be provided by puter systems to manipulate geographic information ? enumerates the service interfaces across which those services must interoperate ? provides a method of identifying specific requirements for standardization of geographic information that is processed by these services ? Standardization at these interfaces enables services to interoperate with their environments and to exchange geographic
