An item may sometimes be described as being a virtual item when it is a representation or non-tangible abstraction of the physical object, or is a functional emulation or simulation of it.

An EU-funded project is boosting Europe's contribution to this on-going international research effort and facilitates the distribution and exploitation of model data.
