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
