Resource-Oriented Computing with NetKernel

Book description

Take resource-oriented computing out for a spin with this hands-on introduction to NetKernel, and discover how ROC can improve the way you design and implement software and software systems. Learn how ROC’s new approach combines core ideas from the REST architectural style with the Unix development model. By using NetKernel to create and then string simple services together, you can develop complex systems that scale as easily as the Internet does. Author Tom Geudens helps you create several NetKernel modules right away, and then walks you through the results to demonstrate their effectiveness.

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