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.

SDM: Smart Data Models initiative

The European open data portal is possibly the biggest open data portal in the world with more than one million free datasets coming from 36 countries.

One of the mechanisms to access its data is the use of the standard of DCAT-AP standard 2.0 which defines its catalogue of resources.

In the repository pending there are two data models, in progress to connect a dataset and a distribution as an additional resource by using NGSI. The idea is to create a script to map this resource into NGSI.

Every data model has a directory with examples of the payloads (json and jsonld) in key-values and normalized formats.

But it also includes examples of csv that it could help to connect the data models for other platforms.

Now, these examples are re-created automatically once a day.

The naming convention for these examples are the same name of the original payload plus a .csv suffix.

An example for the Battery data model examples.

Best.

In the upper menu (option Search descriptions) there is a searchable database of the descriptions for all the properties across the different data models.

This DDBB is updated daily.

Every subject had a file named CONTRIBUTORS.md which compiles all contributors to the different data models in this subject. However, from the point of view of the management, it was not a structured format. Due to this, it is going to be replaced with a new file named CONTRIBUTORS.yaml with the same info but structured so we could manage properly and answer questions like:

• How many contributors collaborate in this subject?
• How many subjects are being contributed by this person?
• What organisations are contributing to the initiative?

Now there is also a field for allocating comments.

The format is friendly enough to be simply edited but at the same time, it can be automatically processed.

Next week CONTRIBUTORS.md will be removed from the different repos.

Now it is based on a responsive interface with these options:

• Sort any column
• Search on any value across the different columns
• 50-pages pagination
