This list is by no means exhaustive and not all may apply to a set of exhibits/artifacts of interest, but having some relations with more restricted meanings than HasDependencyOn or standardizing vaules for natureofdependency would be useful for key kinds of dependencies, e.g. is version derived from. Apparently, as natures of dependencies could vary multiple relations related to a single dependent element must be allowed.
Fanally, should:
• Values for natureofdependency that duplicate meanings of AssertedLinks be allowed?
• HasDependencyOn inherit from AssertedLinks (or less preferably just Assertion)?

this purpose with a tag 'natureofdependency'.
