Depending on the project and domain classification of the organization, a project or solution architect will be responsible for the architectural development of one or more projects that achieve a conversion from the baseline to the target architecture.

Role ultimately responsible for the overall architecture for the entire organization. So has both a global and an abstract scope on the architecture and the use of the architecture repository.

When using an architecture repository, it is important to determine what and how the architecture is modeled. To this end, a metamodel is drawn up by this role. This includes the modeling conventions, cross-language conventions and design of the repository.

Responsible for the use and deployment of the models in the architecture repository. Has a coordinating and controlling task for all modeling roles involved in the architecture. Monitors the consistency of the architecture repository and provides modellers with information and training on the use of the architecture repository.

In addition to drawing up architectures, there are also roles that review and approve the architecture artifacts. For example, by testing for quality, feasibility, but also on the application of the modeling conventions and the organizational metamodel.

Architecture largely consists of drawing up models of the domain in question, often using a standardized (meta) model.

In addition to the use of a modeling language, additional requirements and definitions are drawn up around the Architecture models and products. They are frameworks for architects who develop different types of architectures.

An inventory document describes the aspects that are relevant when mapping a complex architecture, for example the baseline or target architecture. It is part of the analysis and modeling to establish an architecture.

A reference architecture is an abstract architecture in which a number of generic frameworks or building blocks are described. Organization-specific (domain and solution) architectures are drawn up based on reference architectures.

The metamodel describes the model of the architectures. This is often based on an architectural modeling language such as ArchiMate. These architectural modeling languages have also been developed in a metamodel

A list of proposals, in the form of requirements and requirements for the architecture to be drawn up. But also for the metamodel or the modeling conventions of the architectures to be developed.

A model is a schematic and simplified representation of part of the (architectural) system. It is often developed in modeling languages such as ArchiMate or BABoK.
