Image specialisations
in turn be specialised further so that, for example, an X-Ray image can add the func-
tionality of providing the energy of each X-ray photon collected by the observing
instrument.
Each increasingly specialised sub-area will produce increasingly specialised
aspects for their, in this case, images. Each specialisation will introduce additional
functionality.
7.8.5 Higher Level Knowledge Virtualisation
Knowledge Management covers a very large number of concepts. We do not go into
these here but instead note that there are multiple encodings available. Some of these
are discussed in the next chapter.
7.8.6 Access Control/Trust Virtualisation
As with Knowledge Management there are several approaches and implementations.
A virtualisation effort which CASPAR has undertaken is to try to identify a rela-
tively simple interface which can be implemented on top of several of these existing
systems. Access Control, Trust and Digital Rights Management are related con-
cepts, although they cover, in general, distinct functions and different domains. For
example, Access Control can be distinguished from DRM mainly by the following
aspects:
