New option for drafting a data model
In the front page, there is a new option that allows you top to directly create a copy of the template sheet for creating new data models.
Remember that this spreadsheet is done for those unfamiliar with json schema (the official format for the smart data models) to allow them to create a new data model from their knowlege.
The use instructions are in the spreadsheet
Any doubt please let us know at info@smartdatamodels.org
Updated context.jsonld
The context.jsonld for smart data models has been updated to meet json ld requirements. Now they are implementing geojson requirements.
It affects the terms of bbox and coordinates. It could impact those elements having a geoproperty (most of the data models).
Create your data model with a google spreadsheet
NEW VERSION!!
This post became obsolete, go for the new master sheet
This is a resource, especially for those who have limited knowledge of JSON schema.
If you want to create a basic version of a data model (not all JSON schema is implemented), you can use a copy of this spreadsheet as template. This spreadsheet is always available at https://bit.ly/schema_sheet short name.
You need to fill the blue cells for these parameters:
- Subject: Official Subject where this data model should be allocated. (Check the official list)
- DataModel: Official data model name (Only one word i.e. WeatherForecast, no _).
- Title: use to be the name data model name with spaces. (i.e. Weather Forecast)
- Global Description: General text description of the data model. (2 lines is nice)
- Property name: Exactly this, the name of the property. Use camelCase. It would be good to check here whether this property already exists (you can copy and paste). Use those you need and leave one empty after those you filled. Properties below an empty property name are ignored.
- NGSI type: (Property, Relationship or Geoproperty)
- Data type: Type of data in the property. (array and object are not fully implemented)
- Other restrictions: If you are unfamiliar with JSON schema leave it empty.
- Description: Official description of the property.
Once you’ve got the schema, grab some examples (It is always good to review the contribution manual) and you can make a Pull Request on any of the subjects of any domain in Github. Or just use this form.
NOTE 1: The first option will be attended quicker than the second.
NOTE 2: Do not write out of the blue cells (it will be ignored). And do not add or remove cells. The converter script looks for these precise locations in blue.
NOTE 3: Your spreadsheet has to be made public. (anyone with the link), otherwise, the script will not be able to retrieve your data.
Call:
Parameters: (Mandatories)
- sheetUrl: The url of the spreadsheet (if not it takes default spreadsheet in the menu)
Output: A json schema based on the properties defined in the database. This is an alpha version so errors are not managed.
Alpha version for drafting a data model
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
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.”.
Instructions to be listed as a data model adopter of Smart Data Models
It has been updated the format of the list of adopters of the data models (formerly were CURRENT-ADOPTERS.md markdown files), now in it is rename into ADOPTERS.yaml based on this yaml template which allows an automatic processing. (Further announcements could be included in a future).
Further instructions in the page Data Models Adopters how to located in the menu option Data models -> Data Models Adopters How to
Smart water and Smart Environment: Updated WaterQualityObserved in water quality repository
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.
Updated waternetwork datamodels
The 8 data models in the repository dataModel.WaterNetworkManangement in the Smart Water domain have been updated to be aligned with the shared properties of GSMA commons in the shared properties common-schema.json..
This change does not affect the existing data models but with the extensions of these elements.
Improved the database of properties
The database for the searching on data models, properties and their descriptions has been expanded to allow filtering also by :
- NGSI type (one of Property, Relationship or Geoproperty)
- data type (string, number, boolean, array, object, etc)
Additionally, it has been updated containing more than 11.000 items
