2. Licenses and TOS for the Open Data Hub material

The resources that are part of the Open Data Hub Project are subject to different licenses, which are described in section Licenses for Open Data Hub resources. Derivative material built using Open Data Hub material is also subjected to different licenses, depending on its purpose, as shown in Figure 2.1.

The FLOSS four freedoms

The four essential freedoms are the four basic principle to which a software program must comply to be defined free software. As stated on the What is free software? web page (on which you can find a lot more information and details), they are:

  • The freedom to run the program as you wish, for any purpose (freedom 0).

  • The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1).. Access to the source code is a precondition for this.

  • The freedom to redistribute copies so you can help others (freedom 2).

  • The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Licenses for Open Data Hub resources

The Open Data Hub Project processes dataset, possibly supplied by third-party sources (i.e., Data Providers), which may contain closed data; however, only Open Data are returned to the users’ queries.

According to the main goal of the Open Data Hub Project, we have defined licenses for its different components and we use badges across the documentation for a better visibility. As a rule of thumb, we try to do our best to deliver Open Data, by developing Free/Open Source software that is publicly available on github, and by using an Open Standard for the API used to access data.

These licenses are applied to the Open Data Hub components:

  • All the software released within the Open Data Hub is Free software and complies with the GPLv3 license. GPLv3 license Code repositories can be found at https://github.com/noi-techpark.

  • The Datasets currently expose only Open Data that are in the public domain, so they are released as CC0. CC0 license (public domain)

  • The APIs have no license yet, since we are in the process to define which among the CC licenses could fit best. See Figure 2.2 for an overview and quick description of CC licenses and derivative material.

Note

There is an additional clarification about the licence for any content that is retrieved from the datasets in JSON format, which is detailed in Section License of the JSON Responses.

APIs Terms of Service

The Open Data Hub project is already used in production for NOI internal projects, and in particular it is the data hub used by the South Tyrolean tourism portal, www.suedtirol.info.

The public API are in early development and therefore should be still considered as a beta version. If any third party would like to use a stable version of the APIs in its production environment, a special agreement must be signed with NOI techpark. You can contact for any information.
