Getting Involved

There are different possibilities to participate in the Open Data Hub Project, including -but not limited to- to report bugs in the API or errors in the API output, to ask for more datasets to be added to our repository, to make feature requests or suggestions for improvement.

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, App developer, Core Hacker, and Data Provider. You can find out below which type of role better fits with your expertise!

You can also help the Open Data Hub project grow and improve by reporting bugs or asking new features.

…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.

…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.

…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.

…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.

…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:
