Getting Involved


Figure 3 Relations between the actors involved in the Open Data Hub.

The Open Data Hub team welcomes new partners and user to join the project. For this reason, a number of services are offered to help you getting in touch with the project and support you in case you want to either collaborate with the project or simply use the data made available.

The Open Data Hub team envisioned different possibilities to join the project, that are detailed in the remainder of this section, including–but not limited to–reporting bugs in the API or errors in the API output, making feature requests or suggestions for improvement, and even to participate in the development or supply new data to be shared through the Open Data Hub.

Figure 3 shows at a glance the services offered by the Open Data Hub together with the various roles that potential users can play within the Open Data Hub, according to their interest, expertise, skills, and knowledge.

Data Sharing

The Open Data Hub team helps you in various activities: give visibility to your data, identify both suitable, common formats, processing algorithms and licenses to share your data, and to use popular technologies known by application developers.

This service is suitable for Data Providers.

Data Access

The Open Data Hub team supports software development companies to access to real-time data, by making available to everyone a stable communication channel which uses a machine-readable protocol and an Open Data license, to ensure everybody can easily find all the available data.

This service is most suitable for Data Consumers and App developers.

Demo App Development

The Open Data Hub team collaborates with companies to design and develop Proof of Concepts and demo software, released under an Open Source License that use data offered by the Open Data Hub. All the software can then either be used as-is–to show and test its potentials, or as a guideline and inspiration to develop new digital products.

This service is suitable for Data Consumers, App developers, and companies interested in development built on top of the Open Data Hub.

Besides the tasks that you find below, you can also help the Open Data Hub project grow and improve by reporting bugs or asking for new features, by following the directions presented in the dedicated section below.

How to access

This section gives an overview of which tasks you can play when collaborating with the Open Data Hub project.

Depending on your interest on the Open Data Hub Project, we welcome your participation to the project in one of the roles that we have envisioned: User (Data Consumer), App developer, Core Hacker, and Data Provider. Below you can find out a list of tasks that belong to each of these roles; we believe that this list can help you understand which type of contribution you can give to the Open Data Hub project!

As a User I can…
…install and use an app built on top of the API.

Browse the list of available applications developed by third-parties that use Open Data Hub data, choose one that you are interested in, install it and try it out, then send feedback to their developers if you feel something is wrong or missing.

…explore the data in the datasets.

Choose a dataset from the list of Datasets and start gathering data from it, by using the documentation provided in this site. You can then provide any kind of feedback on the dataset: reports about any malfunctions, suggestions for improvements or new features, and so on.

Moreover, if you are interested in datasets that are not yet in our collection, get in touch with the Open Data Hub team to discuss your request.

As an App Developer I can…
…harvest data exposed by the dataset.

Browse the list of Datasets to see what types of data are contained in the datasets, and think how they can be used.

For this purpose, we maintain an updated list of the available datasets with links to the API to access them.

…build an application with the data.

Write code for an app that combines the data you can harvest from the available datasets in various, novel way.

To reach this goal, you need to access the APIs, their documentation, and the datasets. It is then your task to discover how you can reuse the data in your code.

…integrate Open Data Hub data using Web Components.

The Open Data Hub team and their partner have developed a small library of Web Components that can be integrated in existing web sites or used as guidance to develop new Web Components.

…publish my app in Open Data Hub.

As soon as you have developed a stable version of your app, get in touch with us: We plan to maintain an updated list of apps based on our dataset included with this documentation.

No software installation is needed: Go to the list of available applications developed by third-parties that use Open Data Hub data, to the API documentation of each Dataset and start from there, and develop in a language of your choice an application that uses our data.

As a Open Data Hub Core Hacker I can…
…help shape the future of Open Data Hub.

Participate in the development of Open Data Hub: Build new data collectors, extend the functionality of the broker, integrate new datasets on the existing infrastructure, develop new stable API versions.

To be able to become a core hacker, however, requires a few additional tasks to be carried out:

  1. Learn how to successfully integrate your code with the existing code-base and how to interact with the Open Data Hub team. In other words, you need to read and accept the Guidelines for Developers (click on the link for a summary), which are available in two extended, separate parts: Platform Guidelines - Full Version and Database Guidelines - Full Version.

  2. Understand the Open Data Hub Architecture.

  3. Learn about the Development, Testing, and Production Environments.

  4. Install the necessary software on your local workstation (be it a physical workstation, a virtual machine, or a Docker instance), including PostgreSQL with postgis extension, JDK, git.

  5. Set up all the services needed (database, application server, and so on).

  6. Clone our git repositories. To successfully complete these tasks, please read the How to set up your local Development Environment? tutorial, which guides you stepwise through all the required set up and configuration, along with some troubleshooting advice.

  7. Coding. That’s the funniest part, enjoy!

To support the installation tasks and ease the set up of your workstation, we are developing a script the you will do the job for you. Stay tuned for updates.

As a Data Provider I can….
…provide Open Data to the Open Data Hub project.

Share with an Open Data Licence (like e.g., CC0 license (public domain) or CC BY-SA license) the data you own, that can prove interesting for the Open Data Hub, for example because they complement existing data in the Open Data Hub or they pertain to an area which is not yet covered. Let your Open Data be freely used by App Developers in their applications.


A Data Provider is an entity (be it a private company, a public institution, or a citizen) that gathers data on a regular basis from various sensors or devices and stores them in some kind of machine-readable format.

Bug reporting and feature requests

This section explains what to do in case you:

  1. have found an error or a bug in the APIs;

  2. like to suggest or require some enhancement for the APIs;

  3. have some requests about the datasets

  4. find typos or any error in this documentation repository;

  5. have an idea for some specific tutorial.

If your feedback is related to the Open Data Hub Core, including technical bugs or suggestions as well as requests about datasets (i.e. points 1. to 3. above), please insert your issues on the following website:

If your feedback is related to the Open Data Hub Documentation, please insert your issue on the following website, using the template that suits your needs:


You need to have a valid github account to report issues and interact with the Open Data Hub team.

We keep track of your reports in our bug trackers, where you can also follow progress and comments of the Open Data Hub team members.
