Included into the data model a first version for the placement of device. This feature allow a better use of the device data model in the smart sensoring domain .

Automatic creation of examples
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
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
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.
Best
Replaced CONTRIBUTORS.MD by CONTRIBUTORS.yaml
Now in the root of every subject, you can find only the file CONTRIBUTORS.yaml with the current contributors to the data model of the subject.
The old file CONTRIBUTORS.md is being removed.
CONTRIBUTORS.yaml is a structured format that allows automatic treatment globally across the initiative. It compiles the full name of the contributor, his/her organization, and their project and comments if necessary.
If you keep seeing it is because you are not looking at the master branch but in a specific commit (like it happens in the submodules). We update the branches in submodules daily, so tomorrow it will not appear unless you want it to go to former commits.
See one example.
Automated README.md for data models
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
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:
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
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.
Soon there will be another survey for the CONTRIBUTORS.
New data models for Photovoltaic Device
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.
New harmonization repository
In order to provide a more transparent and participative approach to the creation and maintenance of data models, here you can see the three stages for a usual data model to be part of the official list of data models.
1.- Pending is the ‘wild’ zone where developers share their thoughts and create their data models. When finished (ready) they can create a PR on the right Subject repository.
2.- Harmonization is the repository for those new accepted models while they are fine-tuned or completed
3.- Subject means the repository in which the data model is officially published. Once there they are versioned when necessary.
| Pending | Harmonization | Subject | |
| Control of contributions | No | Yes | Yes |
| Scripts for checking | No | Yes (specific) | Yes (only acceptance and on update) |
| Code inside json schema | No | Harmonizing | Local standard

| Versioning | No | No | Yes |
| Managed | Each contributor | Contributor + SDM control | SDM control |
| In domain | No | No | Yes |
| Accept issues | Yes but not managed | Yes | Yes (Here the open ones) |
