A ResourceFunctionSpec specifies a function as a behaviour to transform inputs of any nature into outputs of any nature independently from the way it is provided. It is typically created by a function designer who may not have specific knowledge on realisation architecture (for example using English text explanations with diagrams, like RFC standards, or preferably a machine interpretable language). <br/><br/>NetworkFunctionSpec, OfficeFunctionSpec as well as GameFunctionSpec are examples of specialisation.<br/><br/>The realization/deployment of a ResourceFunctionSpec may be achieved by different ways; either SoftwareSpecification, PhysicalBlackBoxSpec or SoftBlackBoxSpecification.<br/><br/>Examples: manually or automated by software or hardware implementing algorithms etc… without any impact on the definition of the functions itself.<br/><br/>A ConnectionPointSpec is used to describe the information/data input to a ResourceFunctionSpec or output from a ResourceFunctionSpec. This description is captured independently from the way it is realised.<br/>
