A UUID (UuId) is a unique identifier.
Traditionally, UUIDs are 128-bits, and there are techniques for generating them which guarantee their uniqueness.
From the point of view of the LocalResourceManager[1], it simply wants arbitrary blobs of arbitrary length that are unique when compared bit-by-bit.
