• receiving a plurality of reader locations relating to a corresponding plurality of radio frequency identification (RFID) readers;
• receiving, from the data set provider, a second data set member, the second data set member comprising a plurality of tag data from the plurality of RFID readers, where each tag data of the plurality of tag data is read by a corresponding RFID reader from a single RFID tag attached to an object;
• generating an object location based on the plurality of tag data and the plurality of reader locations;
• receiving real-time data from a data source, the real-time data relating to the object;
• converting the real-time data to converted real-time data having the data format specified by the first data set information;
• generating a first data set member from the object location, the tag data, and the converted real-time data, the first data set member comprising the data content and the data format specified by the first data set information;
• and
• sending the first data set member to the subscriber.
