Drafting service for checking properties of a new data model

  By , , , , , , , , , ,

We are in the way of creating a service for those contributors willing to contribute with a complete data model.

The service is under debugging, so it cannot be trusted for production purposes. Let us know issues here

In order to access it has to access this URL (https://smartdatamodels.org/extra/check_properties.php) with this parameter ?urlSchema=[url of the raw access o the JSON schema]

I.e. a complete link could be

https://smartdatamodels.org/extra/check_properties.php?urlSchema=https://raw.githubusercontent.com/smart-data-models/dataModel.Agrifood/60755d5e970f18938a59dcb190a91ac5622c6c11/AgriParcel/schema.json

It returns a JSON payload indicating if this property is available for use (not used in any other data model) or in the case it is already being used what data models are currently using.

Official list of unitcodes

  By , , , , , , , , , ,

Whenever there is measurement it could be necessary to use the unitCode for setting the units for the value.

Now the guidelines for the data model’s creation include the place to find out these unit codes. See section units.

The list of UN/CEFACT Common Code (3 characters) can be download from this page. Or the list directly from here.

Automatic creation of examples

  By , , , , , , , , , ,

In order to reduce the amount of work in the contribution of data models, we have a script that generates the key-values format of a normalized NGSI LD payload.
It has been operated on 46 data models currently in the repository.

In a close future instead of submitting 4 examples, it will be only necessary to include 2 examples, the normalized payloads for NGSI v2 and NGSI LD (the other two would be generated automatically).

Making examples more consistent

  By , , , , , , , , , ,

All the repositories have been normalized in the naming of the core examples. So:

  • Key values in NGSI v2 is named example.json
  • Key values in NGSI LD is named example.jsonld
  • Normalized (default) in NGSI v2 is named example-normalized.json
  • Normalized (default) in NGSI LD is named example-normalized.jsonld

It is possible to have more examples in the directory. And in the same directory of every data model, there are other exports (csv) for the use of the data model users.
The goal is that this 4 examples were present in every data model

Automated README for Subjects

  By , , , , , , , , , ,

As promised the README.md at Subject level explaining the different data models is automated, and therefore there is no need to be contributed by the contributors. See an example here for the weather subject

Thus, the README.md is based on the data models and their descriptions, linking to the current contributors

Soon the README.md for the domain will be also automated.

Automated README.md for data models

  By , , , , , , , , ,

Currently, the README.md at data models level (inside every directory in a Subject) explaining the contents of the data models is automated, and therefore there is no need to be contributed by the contributors. See an example here for the weather forecast.

Thus, the README.md is based on the examples provided, the specification and the model.yaml.

Soon the README.md for the Subject will be also automated.

Incubated data models

  By , , , , , , , , ,

if you are browsing the repository you can realise that now there are several data models ended with the term ‘_incubated’.
This suffix denotes that there will be ‘soon’ a new data model.
The readme in the folder points to the repository where this data model is being created.

Once finished (all the docs, examples, etc) the _incubated suffix will be removed and the data model will be fully included into the data models.
some examples:

Floor_incubated

BuildingType_incubated(published 30-11-21)

PhreaticObserved_incubated (published 31-5-2021)

RainFallRadarObserved_incubated (published 10-5-2021)
etc

Survey to the users of smart data models

  By , , , , , , , , , ,

This is the first survey to the USERS of the Smart Data Models. We want to know what is more important to you and try to prioritize our efforts. This is an agile initiative, therefore we will take into very consideration your comments. Your survey is anonymous although if you wish you can include your email in comments and we will contact you regarding your comments.

You can answer it here.

    Are you, or your organization, a user of FIWARE platform (any enabler)

    New data models for Photovoltaic Device

      By , , ,

    In the harmonization repository, there is a new model name photovoltaic Device. To be completed previously to be incorporated. You can submit an issue on it if interested.

    The Data Model is intended to describe the mechanical, electrical and thermal characteristics of photo-voltaic panels according to : – STC – Standard Test Condition – Sunshine 1000 Wm² / Radiation 1.5 AM / Temp 25° Celsius / Air Masse 0 m/s. – NOCT – Normal Operating Cell Temperature
    – Sunshine 800 Wm² / Radiation 1.5 AM / Temp 20° Celsius / Air Masse 1 m/s.

    The measures performed for STC and NOCT are – [Pmax] Maximum Nominal Power measured in WTT represents Watt.. – [Umpp] Optimal operating voltage measured in VLT represents Volt. – [Impp] Optimal Operating Current measured in AMP represents Ampere. – [Uoc] Open Circuit Voltage measured in VLT represents Volt. – [Isc] Short Circuit Current measured in AMP represents Ampere.

    Additional Information about Data Model: This Data Model can be used directly as the main entity to describe the device [PHOTOVOLTAIC] or as a sub-entity of the Data Model [DEVICE] using a reference by the refDevice attribute.
