Warning message

You can't delete this newsletter because it has not been sent to all its subscribers.

Any update and addtion to the dictionary in place of www.Snap4City.org can be requested to snap4city@disit.org

if you have your own instance of the platform you can define your own dictionary and request a copy of the snap4city.org dictionary to Snap4City@disit.org 

The dictionary is used: (i) during the IoT Device Model definition, (ii) in mapping smart data models FIWARE, and (iii) in creating full custom IoT Devices

Please note that

  • Data Type for time stamps are ISOString: YYYY-MM-DDTHH:mm:ss.sssZ which can be obtained by using function toISOString() of JavaScript on variables of kind Date()
  • In some cases, according to the Value Unit selected the possible Data Types would be restricted. These constraints are directly applied in the user interface tool of the IoT Directory.
  • You should avoid to use as ValueName a string used for Value_Type, Value_Units and Data_Type
  • Value_Type, Value_Units, Data Types cannot have spaces in the their definition
