Now the README file of every data model includes a link to the generator of NGSI-LD payloads compliant with the data model.
As you can see in the image below there is a new section “Dynamic examples generation”
There is the sentence “Link to the Generator of NGSI-LD payloads compliant with this data model. Refresh for new values”. By clicking the Generator link an example of payload appears on the web page. Refreshing (F5) generates new payloads.
Now all data models have an interactive specification. (As long as they have examples)
This is the first step to deeper interactive services for every data model contributed.
See the example for weatherForecast.
The file common-schema.json compiles those properties massively used across the different data models in the different domains.
The property userAlias has been included to store those anonymous identifiers of a user that cannot be traced back to the user.
It can be referenced in any data model just by including this code
“$ref” : “https://smart-data-models.github.io/data-models/common-schema.json#/definitions/userAlias”
This a general review of the contributions’ manual with these changes:
- Recommendation how to document a property that is an object referencing to a shared schema
- Change order in the elements (schema recommendation is the most demanded documentation and it is being placed at the beginning)
- Minor reviews, contact point, etc.
Located in the upper menu of the site.
It has been updated the database for searching properties, two main improvements:
- Performance (now it is a database query instead of the former static file)
- The reference model of the property
- The format (uri, date-time, etc) for string properties.
OPCUA is a protocol for machine to machine communication and there is a specific subject for mapping this standard with NGSI is being developed.
MotionDeviceSystem: provides a representation of a motion device system as an entry point to the OPC UA device set. This instance organizes the information model of a complete robotics system using instances of the described ObjectTypes. A motion device system may consist of multiple motion devices, controllers, and safety systems
This is an alpha version (so you can expect errors and not being complete). Use it at your own risk. Please report errors and suggestions at email@example.com
- schemaUrl: The link to the RAW version of the json schema (see example)
- email: your email
Use any data model from Smart Data Models initiative and paste it into the form. Then you’ll get a page with a random payload compliant with the data model. Refresh for more.
You can also use this form
A new subject is being created for the integration of OPC UA standards for the Smart robotics domain.
Initially, there is a data model already in the incubated repository that hopefully will be validated soon and it will become official.
Update 25-5-2021: The data model has been officially released here https://github.com/smart-data-models/dataModel.OPCUA/tree/master/MotionDeviceSystem.
In the directory utils of the umbrella repository data-models there is a new python script that checks if a schema is properly documented and if the payload is correctly located and validates against the schema.
