The memory layer can have the property of sharing within a layer of collective memory, but only as vetted by the Peer. This is consistant with the notion that the Peer may have a complex interior. The anticipation layer can be opened up to periodic revision (by an human awareness) to reflect the contingences of the environment. These contingences are called affordance in a well-defined literature that has become part of the basis of knowledge science.

In this way, the three layer {CPU, Peer, Information} architecture may provide the algorithmic context for services as required by Peer-2-Peer systems. These services include transaction and data mining services typical of Client-Server computer networks. This seemed to be the objective of the two presentations.

The tri-level architecture {sub-structure, middle world, ultra-structure} provides an architecture for knowledge science support of knowledge technologies.
