PBCore 2.0 can be used to express “abstract,” or metadata-only assets.
These assets simply do not have any instantiations, and might serve to represent a high level idea such as a television for which there is no single physical or digital instantiation.
The descriptive metadata within such an assets may be referenced from within other assets. For example, programs within a series can reference the series record and vice versa. This can save the effort of creating redundant metadata.
