Resumen
This paper uses an approach drawn from the ideas of computer systems modelling to produce a model for information itself. The model integrates evolutionary, static and dynamic views of information and highlights the relationship between symbolic content and the physical world. The model includes what information technology practitioners call ?non-functional? attributes, which, for information, include information quality and information friction. The concepts developed in the model enable a richer understanding of Floridi?s questions ?what is information?? and ?the informational circle: how can information be assessed?? (which he numbers P1 and P12).
