Alpha version for drafting a data model

  By , , , , , , , , , ,

In case you are not an expert for creating a JSON schema (one of the elements of a data model)
On this page, you have a spreadsheet for helping with the first steps.


1.- Fill the spreadsheet with the names of the properties for your model

2.- fill the NGSI type (Property, Relationship or Geoproperty)

3.- In case of property, fill the data type (array and object types are currently not completely supported)

4.- Fill in the description

5.- Click the button, the page will reload

6.- voila! you have your json schema below the spreadsheet, just copy and paste into your favourite editor.

The python code for it is also made public in the utils directory in the data models repo.

Include levels of privacy of properties in their description

  By , , , , , , , ,

The privacy of the data contained in a property has been under discussion for the documentation of any property.

Now there is a first version on how to implement it.

The contribution manual has been updated for this possibility. See the specific slide about it.

Privacy clause: Privacy:’[high/medium/low]

Describes if the property has any kind of information related with personal data. Current options:

  • No clause: (default) this property does not contain personal data
  • Privacy:’high’: Those properties that refer to data on ideology, union affiliation, religion, beliefs, racial origin, health or sexual life.
  • Privacy:’medium’. Those properties related to the provision of financial solvency and credit services of people and those that contain definition of characteristics or personality and that allow evaluating certain aspects of personality or behavior of people.
  • Privacy:’low’.  Those properties that contains personal data different from the rest of types.

Example:

“refUserDevice” :{

“description”: “Property. Model:’http://schema.org/Text’. Privacy:’low’. An object representing the current device used by the User.”.

Smart water and Smart Environment: Updated WaterQualityObserved in water quality repository

  By , ,

The data model WaterQualityObserved has been expanded to include 3 new properties:

  • BOD: Biochemical oxygen demand (BOD) is the amount of dissolved oxygen (DO) needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period
  • COD: Chemical oxygen demand (COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution
  • PO4: Concentration of phosphates

Additionally, the data model of WaterQualityObserved has been moved from the dataModel.Environment repo to the dataModel.WaterQuality subject.

In order to preserve the relationship with the SmartEnvironment domain the subject dataModel.WaterQuality has been linked to it.

All specifications updated

  By , , , , , , , , , ,

All the specifications (the text descriptions of the data model located in the /doc directory of each daat model) for the different domains and languages (currently French and Spanish besides English) have been updated to the new format. See an example in Spanish and French.

All of them are generated automatically from the json schema (which is the unique source of truth for the data model)

The contribution manual explains further details.

Raise an issue for any point you find in the new format.
