    Include userAlias in common-schema.json

    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

    “userAlias”: {
    “$ref” : “https://smart-data-models.github.io/data-models/common-schema.json#/definitions/userAlias”
    }

    Updated the contribution manual

    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.

    Update the database for searching properties and descriptions

    It has been updated the database for searching properties, two main improvements:

    1.  Performance (now it is a database query instead of the former static file)
    2.  The reference model of the property
    3.  The format (uri, date-time, etc) for string properties.

     

    Alpha version of the service for generating an NGSI-LD payload based on a Smart Data Model

    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 info@smartdatamodels.org

    Call: https://smartdatamodels.org/extra/ngsi-ld_generator_v0.92.php

    Parameters: (Mandatories)

    • schemaUrl: The link to the RAW version of the json schema (see example)
    • email: your email

    Example: https://smartdatamodels.org/extra/ngsi-ld_generator_v0.8.php?schemaUrl=https://raw.githubusercontent.com/smart-data-models/dataModel.Streetlighting/f56f5a7933ab05d7fce1d5adc0847f25a099cdb4/StreetlightModel/schema.json&email=alberto.abella@fiware.org

    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

      This form generates a NGSI-LD payload compliant with a json schema from Smart Data Models.

      After clicking it will appear a message confirming the submission

      It will take a while to redirect to the feedback on a specific page

      Thanks for being patient

      Script for checking a data model submission

      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.

      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).
