Data Science: Metamodel (Definitions)

"Model of a model that dictates the rules for creation of modeling mechanisms like the UML" (Bhuvan Unhelkar, "Process Quality Assurance for UML-Based Projects", 2002)

"A description or definition of a well-defined language in the form of a model." (Anneke Kleppe et al, "MDA Explained: The Model Driven Architecture™: Practice and Promise", 2003)

"A model that defines other models. The UML metamodel defines the element types of the UML, such as Classifier." (Craig Larman, "Applying UML and Patterns", 2004)

"A description of a model. A meta model refers to the rules that define the structure a model can have. In other words, a meta model defines the formal structure and elements of a model." (Nicolai M Josuttis, "SOA in Practice", 2007)

"The model of a language used to develop systems. In the case of UML, the definition of UML itself is the metamodel." (Bruce P Douglass, "Real-Time Agility: The Harmony/ESW Method for Real-Time and Embedded Systems Development", 2009)

"A description of a model. A meta-model refers to the rules that define the structure a model can have. In other words, a meta-model defines the formal structure and elements of a model." (David Lyle & John G Schmidt, "Lean Integration", 2010)

"1.Generally, a model that specifies one or more other models. 2.In Meta-data Management, a model of a meta-data system or a data model for a meta-data repository." (DAMA International, "The DAMA Dictionary of Data Management", 2011)

"Model that describes how and with what the architecture will be described in a structural way (model of the model)." (Gilbert Raymond & Philippe Desfray, "Modeling Enterprise Architecture with TOGAF", 2014)

"When common sets of design decisions can be identified that are not specific to any one domain, they often become systematized in textbooks and in design practices, and may eventually be designed into standard formats and architectures for creating organizing systems. These formally recognized sets of design decisions are known as abstract models or metamodels. Metamodels describe structures commonly found in resource descriptions and other information resources, regardless of the specific domain."
