The Metamodel defines how processes are captured within Stages. It defines which process elements exist within a process, how they are associated with each other and how each element type is visualized to the users.
Metamodels are configured on the server by the Stages administrators.
In the default configuration, a metamodel named Unified Configuration is installed, which captures twenty years of customer experience how to best model engineering processes. With the Unified Configuration metamodel, processes are defined by modeling four different perspectives of engineering processes and connecting them with each other:
Derivatives of this metamodel or completely customer-specific metamodels can be configured, typically in collaboration with Method Park consultants.
See here how metamodels are being used to navigate and understand processes in Stages.
Stages can support multiple metamodels at the same time. Each workspace and every process version within each workspace can have a different metamodel.
