New Agent and Dataset data models in DCAT-AP subject

DCAT-AP is the standard for publication of information in open data portals in the EU and other countries. Based on the 2.o.1 version these data models are mapping these two classes agent into AgentDCAT-AP and Dataset.

In the subject datamodel.DCAT-AP there are two data models, AgentDCAT-AP. and Dataset for describing these classes,

  • AgentDCAT-AP. Agent Schema meeting DCAT-AP 2.0 specification
  • Dataset. Dataset Schema meeting DCAT-AP 2.0 specification

The rest of clasess (distribution, etc) are in progress in the incubated repository

Release of software for Smart Data Models initiative

According to the last open session, the script for the creation of the model.yaml file (see this example) file which is present in every data model has been released.
It is a python 3.6 script you can access in the utils directory of the initiative.
source code available.

Collaboration with existing data models in progress.

If you are willing to collaborate with some of the data models currently in progress you can now access a list of projects in the new option in the main menu.

If you are willing to launch your own project for the creation or update of data models you can fill this form, to ask for permissions in incubated repository. Once received permissions will be granted. Also in the main menu.

Microsoft digital twins export DTDL in beta

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).



New method for drafting the json schema for a new data model

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.

OASC Joins the Smart Data models initiative

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.

Extended statistics of the site

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.

Geojson features format examples available at examples directory

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:
