The ISO/IEC 19763 multipart International Standard specifies a metamodel framework for interoperability. ISO/IEC 19763-12:2015 specifies a metamodel for registering information models. This metamodel was developed taking into account two distinct types of information models such as - those that are used to document the information requirements of a particular area of interest, and - those that represent the structure of a database which are often expressed using a Database Definition Language (DDL).
