We have created an export of Smart Data Models in DTDL format. You’ll see them in the root directory named schemaDTDL.json.
A bit more than 500 models have got it because we are in the process of a final complete mapping between the possibilities of JSON schema and DTDL.
This is the first version for testing purposes and they are not meant to be ready for production. Anyhow, we welcome any feedback on them.
See this example schemaDTDL.json, and a tool for finding all of them is available here. (Same tool for any other search).
A new tool (capable of the creation of more complex data models) is available at the menu “Draft a data model”.
It is an external tool that simplifies the json schema needs.
Hope it speeds up the development of new data models and simplifies it for newcomers to this syntaxis.
Anyhow this is the best guide (simple and straight to the point we know)
It is also available at the learning zone in the upper menu.
The JSON schema is our single source of truth compiling into a single document the technical description with the definitions of every element in the data model.
Open and Agile Smart Cities (OASC) has joined the Smart Data Models initiative. Today, 8th of June, it is announced officially their commitment with the principles of the initiative and as a member of the steering committee of the initiative together with TMForum, IUDX and FIWARE Foundation to provide open and free data models for their use in the development of smart applications.
OASC organization accounts with more than 150 cities in Europe, North and south America, Japan and Australia. They will join those cities grouped by other of the partners of the initiative IUDX, public entity of the Indian government for the data interchange between Smart cities in India.
Thus OASC will conscientiously support the adoption and promotion of Smart Data Models and will promote to its membership Smart Data Models in the context of OASC MIMS. FIWARE agrees to promote OASC as the global community of practice for cities and by cities concerning the digital transformation of cities, towns, and rural areas, in particular in but not limited to those regions where OASC does not yet have a presence.
This allows to align common efforts to support the models available in the initiative and to dissemination them worldwide.
Now there is a new page statistics with the main statistics regarding the content of the site.
It can also be found from the More stats link in the widget on the upper right corner of the front page.
Those data models containing examples with a geoproperty, now there also include another file named: example-geojsonfeature.json with this format.
So not all the data models include this example, which is generated automatically (so there is not a need to be contributed).
See an example: https://github.com/smart-data-models/dataModel.PointOfInterest/blob/master/PointOfInterest/examples/example-geojsonfeature.json
Geoproperties were formerly not documented because it was not possible to include the description into the definition of the data model.
Previously, the definition of Geojson property was retrieved from the original source, which prevents the documentation to be added. No its has been cloned into the common-schema.json, and the description has been added. As a consequence, they appear in the specification of all data models (all of them have been updated) tonight.
Additionally, the schema checker (The test which assesses if a JSON schema is properly documented) no longer accepts any undocumented property (Example). So if you want a data model to be accepted then you need to get a 0.
The contribution manual has been adapted accordingly.
The #FIWARESmartFest. From 8-10 June, is a three days online event with >100 speakers from around the globe, and 35 hours “live on air” sessions of exciting deep-dives showcasing the power of #opensource, outstanding use cases, trending topics in tech, the FIWARE Accelerator DAY, networking opportunities on AirMeet, and much more.
On June 9th 18:00 CEST we will hold the Smart Data Models session with these speakers (alpha order):
- Alberto Abella (Data modeling Expert, FIWARE Foundation)
- Gert De Tant. Chief Technical Architect. OASC
- Iván Dvojak. (Marketing Director, Tourism Posadas, Province of de Misiones, Argentina)
- Pierre Gauthier. (Chief API Architect at TMForum)
- Antonello Monti. (Director ACS / Chair Automation of Complex Power Systems at RWTH University)
- Abhay Sharma. (VP Engineering, IUDX Program Unit, SID, IISc)
Have a look and don’t forget to grab yourself a free ticket. https://bit.ly/3bcRn0E

There is a panel during the session and we expect that one or two questions could come from the attendants, or you can send it now at firstname.lastname@example.org
Coming soon the detailed contents of the session.
In the main menu option
Generate NGSI examples -> Geojson features format
This option allows you to generate random payloads compliant with a data model in Geojson features format.
The README of the different data models now contains a new option, to export the payloads as a geojson feature.
It is a new line at the README of every data model. It provides actual results when the data model has Geoproperties. Otherwise, a warning message is replied to the user.
Find here the minutes of the open session.
As a reminder, open sessions are really open. Every Monday 14:00 CEST. You just need to connect to this link https://bit.ly/smartdatamodels and if you want to present something edit this presentation and include your slides.
The open session is a 30.minutes meeting with 3 objectives:
1.- Show last developments. OPEN-SESSION-SMART-DATA-MODELS
2.- Answer questions regarding existing or coming data models
3.- Presenting to the community
There were comments about new data models to be contributed in the water sector and how to run a quick contribution.
