ASOT (Authoritative Source of Truth)

An authoritative source of truth (ASOT) refers to an instance, such as a system, that applies expert standards and rules to establish whether a digital artifact is valid and originates from a truthful source.  
 
Once the verification is done, ASOT plays a key role in preserving the native traceability of a source. A source's information (assets, versions, links, etc.) is maintained in the configuration and can be consulted at any moment.
