12. A system, comprising: a processor; a component, implemented using the processor, that processes an attribute value that is measured via a sensor or derived from one or more values received from one or more sensors; a component, implemented using the processor, that identifies attribute value requests related to the attribute value that meet predetermined criteria which cause the attribute value to be pushed to one or more clients; a component, implemented using the processor, that mediates multiple instances of the attribute value to produce a mediated value and additional information associated therewith, in response to identification of one or more requests and further in response to a determination that the multiple instances of the attribute value are available; a component, implemented using the processor, that pushes a selected value, the selected value being one of the attribute value or the mediated value; and a component, implemented using the processor, that processes the additional information, the additional information including at least one of uncertainty or accuracy information, a timestamp of when the selected value was created or supplied or was most accurate, an indication that the selected value is a constant, indications of restrictions on whether the availability of the selected value is available to a specific client, data type, units, a format version, a name, or generic attribute property supplied by a client, history information, an indication of the supplier of the attribute, an indication of equivalent attributes, indications of clients that have registered for the attribute or consumed values for the attribute, descriptions of clients in order to track statistics, information to be used to evaluate characterization module efficiency or to facilitate process optimization, an indication of a verification of accuracy, a consumer rating or reputation based on input from a set of clients, a cost to use the selected value, future availability of the attribute value, or a version of the attribute, said component that processes the additional information being configured to associate a time stamp to the attribute value in response to receipt of the time stamp, said component that processes the additional information being configured to associate accuracy information to the attribute value in response to receipt of the accuracy information, said component that processes the additional information being configured to associate the accuracy decay information to the attribute value in response to receipt of the accuracy decay information, said component that processes the additional information being configured to convey that the attribute value is a constant in response to the attribute value being the constant, and said component that processes the additional information being configured to associate information, which is associated with clients that are intended to have access to the attribute value, with the attribute value to restrict access to the attribute value to the intended clients.
18. The system of claim 12 , wherein the component that pushes the selected value receives an indication of the attribute value or a mediated value; wherein the component that pushes the selected value receives an indication of a client intended to receive the attribute value or the mediated value; wherein the component that pushes the selected value determines if additional information is associated with the attribute value or the mediated value, and retrieves the additional information; and wherein the component that pushes the selected value delivers at least one of the attribute value or the mediated value or the additional information to the intended client.
