Principles

1. A resource is an abstract set of information. 2. Each resource may be identified by one or more logical identifier. 3. A logical identifier may be resolved within an informational context to obtain a physical resource-representation. 4. Computation is the reification of a resource to a physical resource-representation. 5. Resource-representations are immutable. 6. Transreption is the isomorphic, lossless transformation of one physical resource-representation to another. 7. Computational results are resources and are identified within the address space.
