          Description

          Mauro Cruz sent a message using the contact form at
          https://catalogue.fiware.org/.

          Hello.

          I would like to know if it is possible to consult older data using orion
          Context Broker.

          EG: I have a temperature attribute and the value is constantly changing
          (4,5,9,10,30,2). In the examples and specification i had the impression it is
          only possible to consult the latest value (in this case 2).

            Dear Mauro,

            By design, the Orion Context Broker only keep the last value that it is received, if you want to keep a historical information you should subscribe the Orion with a well-known database using Cygnus GE or to a STH-Comet (a historical database).
