| - | The digital viewpoint converts **[[mbse:digital_artifact|digital artifacts]]** into the contents of a **[[mbse:digital_view|digital view]]** [1]. It uses descriptive models to define, assemble, layout, and present digital artifacts in a digital environment; such that, they serve specific activities performed by stakeholders. The digital viewpoint identifies digital artifacts it needs from an **[[mbse:authoritative_source_of_truth|authoritative source of truth]]** to produce the digital view. In addition, the digital viewpoint defines what a stakeholder-network wants to view from its **[[mbse:digital_engineering_ecosystem|digital engineering ecosystem]]**. The digital viewpoint may be unique for stakeholders at any stage of the system lifecycle or any component of the supply chain. The viewpoint is digital because it is applied to a set of digital artifacts using software and digital technology to produce the digital view. A creator of a digital viewpoint would design it to fulfill the point of view of the stakeholders [1]; thus, they can perform decision-making activities, conduct their responsibilities, or both. The digital viewpoint defines one or more digital artifacts, the standards and conventions to compile the digital artifacts, or the operations to present digital artifacts in a variety of digital multimedia formats [1]. The digital viewpoint may include models, designs, or computer algorithms that specify the type, structure and organization of a digital view’s content. Thus, the digital viewpoint is a model for digital multimedia presentations of digital artifacts based on stakeholders’ point of view, authoritative source of truth, and model formalisms [1] | + | The digital viewpoint converts **[[mbse:digital_artifact|digital artifacts]]** into the contents of a **[[mbse:digital_view|digital view]]** [1].

| - | The **[[mbse:digital_engineering|digital engineering]]** community formed the concept of a digital viewpoint out of a need to describe how engineering practitioners use sources and types of digital artifacts, like models, and assemble and present them in forms that diverse stakeholders need and understand. The DE community borrowed the original concept from the system architecture community and re-conceptualized it to fit the digital engineering community’s need to leverage digital technologies to create, exchange, and present their digital work products. However, it is more than a static document that specifies the digital view. It may be a digital model of the digital view using standards such as Information Flow Modeling Language (IFML). Alternatively, it may be an application-programming interface (API) or other executable software code that assembles digital artifacts and renders the digital view according to the design. | + | The **[[mbse:digital_engineering|digital engineering]]** community formed the concept of a digital viewpoint out of a need to describe how engineering practitioners use sources and types of digital artifacts, like models, and assemble and present them in forms that diverse stakeholders need and understand.
