In the example architecture of FIG. 14, the software architecture 1406 may be conceptualized as a stack of layers where each layer provides particular functionality. For example, the software architecture 1406 may include layers such as an operating system 1402, libraries 1420, applications 1416 and a presentation layer 1414. Operationally, the applications 1416 and/or other components within the layers may invoke application programming interface (API) API calls 1408 through the software stack and receive messages 1412 in response to the API calls 1408. The layers illustrated are representative in nature and not all software architectures have all layers. For example, some mobile or special purpose operating systems may not provide a frameworks/middleware 1418, while others may provide such a layer. Other software architectures may include additional or different layers.
