UMID Applications in Practices
The unique material identifier (UMID) is a SMPTE standard identifier that globally uniquely identifies audiovisual (AV) material. Because it is a core component of the Material Exchange Format and Advanced Authoring Format, it has been also handled by products claiming support for these formats. However, its intended use as a globally unique identifier to link AV material to its metadata has seldom been seen in practice. This paper aims to achieve its original intention by introducing the concept of a UMID-managed domain, where all AV materials are fully managed via their UMIDs, resulting in any AV material being unambiguously retrieved by its UMID. Another important aspect of the UMID-managed domain is that the domains from various products can be merged to produce a wider domain covering the entire system. To achieve this, however, the UMID resolution protocol language spoken by those products needs to be standardized. A couple of basic proposals are presented for further discussions.
