Data model README improvement

The of every data model provides the links to the different translations of the specification. These sentences are now in their original languages.

Additionally, these links now take to the specification in GitHub and stop prompting to be downloaded.

Other information available in the README include:

  1. Links to the automatic creation of examples in NGSI-LD format
  2. Links to the actual examples of the use of this data model in 4 differnt formats

This format update will be completed today for all data models.

If you can think of other improvements please let us know.

Update the specs

Many of the contributors of the data models are providing changes into the 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

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

See the contributors file.


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.


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)
