Accessor
An Accessor is a NetKernel software component that embodies a URI addressable function or service.
Accessors often provide transformation services. Accessors may also act as
external client gateways to resources outside of NetKernel.
Accessors are contained within modules. The module definition provides a mapping of a URI address space to the accessor.
Requests on this URI address space invoke the execution of the accessor.
The use of the term "Accessor" is very deliberate. An Accessor should be thought of as providing access to
the representation of a URI addressable resource.
Accessors may call other accessors by issuing further requests to the URI address space.
