Update the specs
Many of the contributors of the data models are providing changes into the spec.md and its translations.
Fortunately, this is not necessary. You just need to provide the changes in the descriptions included in the schema.json file of each data model.
Now in order to save time for the contributors, a warning message has been included in the specs.
The link takes you to the contribution manual section where the specification is described.
Open Session about Smart Data Models. Monday 14:00
Every week till there will be a 30 min live session to :
- Make questions about any of the data models
- Sharing experiences (maximum 5 minutes)
The agenda for the first 5-minutes slots is this. The 3

New Subject dataModel.WifiNetwork and two new data models AccessPoint and WifiPointOfInterest
The subject dataModel.WifiNetwork is being created and two new data models in it. These two are focused on the availability of wifi in a Smart city.
Coming from the Smart city of Valencia in Spain
- AccessPoint. This entity describes an Access Point which is a networking hardware that generates a wireless network and allows other Wi-Fi devices to connect to it
- WifiPointOfInterest. This entity describes a Point of Interest that has a wireless network

New subject dataModels.MachineLearning and 3 data models
There is a new subject dataModel.MachineLearning and three data models.
- MLModel. Data model for compilation of the elements of a machine learning model.
- MLProcessing. Data model for compilation of the elements about the execution of a machine learning model.
- SubscriptionQuery. Subscription Query model for Machine Learning models
They are located on the CrossSector domain.
Thanks to the FIWARE4Water project.
German translation available / Deutsche Übersetzung verfügbar
Now there is a specification translated into German available for all data models in the initiative. so it becomes official like French one and Spanish.
The translation is made automatically but it seems to be good enough.
Enjoy
NGSI-LD key values service in the README of every
In the README of every data model now there is a new line in the Dynamic examples section, under the text
“Link to the Generator of NGSI-LD keyvalues payloads compliant with this data model. Refresh for new values”
The link provides an example of a NGSI keyvalues payload with values compliant with the data types of this smart data model but generated randomly (so it does not look like static examples which actually are coming from real examples)
New data Model: SeaConditions in weather Subject
There is a new data model in the dataModel.Weather subject, SeaConditions
SeaConditions. This entity contains a harmonized geographic description of sea conditions
New service: Generate a NGSI-LD payload keyvalues format compliant with a Smart Data Model
There is a new service for users, which is the ability to generate an example payload compliant with a specific data model in key values format. Previously it was available the normalized format.
Options are located in the main menu (Generate NGSI examples)
Update of the contribution manual. Process image
We have drafted the publication process for new data models and for updates.
It’s the first page of the contribution manual and every box (not in this image) has links to the tools/resources to be used.
Hopefully, it will be more straightforward to be understood.
