An Asset Distribution represents a particular physical embodiment of an Asset, which is an example of the FRBR entity manifestation (the physical embodiment of an expression of a work). An Asset Distribution is typically a downloadable computer file (but in principle it could also be a paper document) that implements the intellectual content of an Asset. A particular Asset Distribution is associated with one and only one Asset, while all Distributions of an Asset share the same intellectual content in different physical formats. Asset Distributions themselves are not versioned.
