-The authoritative source of truth for a **[[mbse:​digital_artifact|digital artifact]]** serves as the primary means of ensuring the credibility and coherence of the digital artifact that its creators share with a variety of stakeholders. ​Stakeholders ​from diverse organizations and distributed locations ​have authorized access ​to observe, analyze, and use digital artifacts ​validated by an authoritative source ​of truth. The owners of digital environments or the community for **[[mbse:​digital_engineering_ecosystem|digital engineering ecosystems]]** provides stakeholders with appropriate access to shared, current, and consistent information over the lifecycle of systems. The authoritative source of truth assures confidence in the quality of the digital artifact across disciplines,​ domains, and life cycle phases. ​+The authoritative source of truth for a **[[mbse:​digital_artifact|digital artifact]]** serves as the primary means of ensuring the credibility and coherence of the digital artifact that its creators share with a variety of stakeholders. ​It gives stakeholders ​from diverse organizations and distributed locations ​the authorization ​to access, analyze, and use valid digital artifacts ​from an authoritative source.

 In order to do so, a digital artifact’s authoritative source of truth should meet four conditions. First, the digital artifact originates from a repository recognized by a governing entity as a [[https://​whatis.techtarget.com/​definition/​system-of-record-SOR | System of Record (SoR)]]. Second, the majority of experts accepts the credibility,​ accuracy, and trustworthiness of a digital artifact because it meets their “criteria of truth” [1]. For example, in the **[[mbse:​model_based_engineering|Model Based Engineering (MBE)]]** domain, the digital artifact may meet the criteria of truth when most stakeholders agree that the preponderance of evidence upholds the validity of the digital artifact because it represents a commonly accepted perspective of reality [2]. Third, a digital artifact’s source is an authoritative when most experts agree that the source is legitimate. Finally, the digital artifact originates from a technological system that maintains its integrity and reinforces the conditions. If the SoR satisfies the four conditions; then, it is the Authoritative [[https://​www.linkedin.com/​pulse/​difference-between-system-record-source-truth-santosh-kudva/​| Source of Truth (SoT)]] for its digital artifact [3].  In order to do so, a digital artifact’s authoritative source of truth should meet four conditions.

-An Authoritative Source of Truth (ASoT) architecture provides the framework to ensure the validity and truthfulness of digital artifacts as they are managed throughout their lifecycle and the integrity of the enabling technological systems. According to a presentation by participants of an Air Force Study [4], the ASoT architecture owners should organize it according to technical platforms or domains and not by specific programs. The platform or domain focus of the ASoT architecture maximizes the usability of the digital artifacts by the communities of practicing engineers [4]. A governing entity that determines Systems of Record (SoRs) does so on the basis of digital artifacts used in its domain. For example, SoRs may include a requirements database, engineering cost data, a model-based systems engineering (MBSE) environment,​ and computer aided design (CAD) systems for transport aircraft. ​ In order to satisfy the conditions for authority, the ASoT architecture must maintain the integrity of these technological systems in order to ensure that one – and only – one SoR exists for each digital artifact. As such, there is a one-to-many relationship between an ASoT and many digital artifacts. ​+An Authoritative Source of Truth (ASoT) architecture provides the framework to ensure the validity and truthfulness of digital artifacts as they are managed throughout their lifecycle and the integrity of the enabling technological systems.
