The opendata.swiss portal

1. What is opendata.swiss?

opendata.swiss offers a central point of access to open, i.e. freely accessible data from the public administration (“open government data”, or OGD). The authorities involved make their data available on the portal. It is operated by the Federal Archives. You can find more information here.

2. Who is involved in opendata.swiss?

An overview of the organisations responsible for the portal can be found here. These organisations are working together as part of the OGD Switzerland project. All the data owners are listed under organisations. opendata.swiss is operated by the Federal Archives.

3. What is the purpose of opendata.swiss?

In 2014 the Federal Council approved the Open Government Data Strategy for Switzerland 2014-2018. It stipulates that “Official data should be published without undue delay and be findable and made accessible via a central directory.” opendata.swiss creates this central directory. It facilitates access to the data and, thanks to the use of open data formats and uniform conditions of use, encourages its exploitation.

4. How does opendata.swiss relate to existing specialist data infrastructures? What is the benefit of having an additional portal?

The opendata.swiss solution architecture provides central public access to the project partners’ data to complement the existing specialist data infrastructures of the data owners (e.g. geo.admin.ch and bfs.admin.ch) via which the latter already provide access to their data and will continue to do so. The portal makes it possible for the first time to search for data from the project partners in a single catalogue rather than having to access a number of sites, as was previously the case. In addition, the data on opendata.swiss are all made available with the same metadata and subject to uniform conditions of use. This reduces the effort involved in searching for data and also facilitates comparisons or combinations of different data.

5. How can I contact opendata.swiss?

Questions about the portal or the OGD Switzerland project can be submitted using the contact form. If you have questions regarding a particular dataset, please contact the author indicated in the dataset.

Data on opendata.swiss

6. What conditions govern use of the data?

The terms of use for datasets on opendata.swiss are essentially based on the existing legal framework. The symbols next to each dataset indicate what use is permitted. All data owners use the same symbols. This page explains the various terms of use.

7. How can I find out about new data?

The Federal Archives announce new data on their Twitter account using the hashtag #ogdch.

8. How can I propose the publication of further data?

We welcome suggestions for the publication of further datasets on opendata.swiss. Please use the contact form. We will collate your requests and establish with the data owner whether publication is possible.

9. Can I publish data from my organisation on opendata.swiss?

The Confederation, cantons and communes as well as other organisations with a mandate from the state can normally publish their data on opendata.swiss. Please feel free to contact us. Detailed information on publishing your data can be found in the OGD Handbook.

The OGD Switzerland Strategy and project

11. What is the OGD Strategy?

The Open Government Data Strategy for Switzerland was approved by the Federal Council on 16 April 2014. It sets out the goals of OGD in Switzerland and defines the next steps in open government data until 2018.

The OGD Strategy for Switzerland is binding for the federal administration. Implementation is being coordinated centrally by the Federal Archives. On the basis of the strategy, the federal government aims to work with the cantons and communes to introduce OGD jointly throughout Switzerland. opendata.swiss is a measure derived from the OGD Strategy.

12. What is the OGD Switzerland project?

The OGD Switzerland project implements the OGD strategy. The project is being overseen by the Federal Archives, with the involvement of numerous other authorities at all federal levels. opendata.swiss was developed as part of this project.

The project is also part of E-Government Switzerland, the joint programme of the Confederation, cantons and communes to promote information and communication technologies that are economically advantageous and close to the citizen.

General questions on open government data (OGD)

13. What is open government data?

The term “open government data” refers to data from public authorities that is available for secondary use by all interested parties, free of charge and ideally in machine-readable form. On opendata.swiss you can find a wide range of datasets such as Swiss communal boundaries, population statistics, current weather data, historical documents and a directory of Swiss literature. Often the data are made available as complete datasets which users can then display, edit or combine to create applications and visual representations that reveal new interrelationships using existing data.

The concept of open government data is already widespread in Europe, while in Switzerland only the City of Zurich and the Confederation so far have a dedicated portal for their data, in the form of opendata.swiss.

Examples of existing data portals:

15. Does open government data ensure data protection?

OGD does not normally publish any personal data; the datasets are aggregated and anonymised. They may not be published in a form that permits them to be traced back to individuals. This is a prerequisite for making such data freely accessible – a goal that is explicitly set out in the OGD Strategy for Switzerland (section 5.2, page 9).

Personal data are only published on opendata.swiss if there is a legal basis for publication. Additionally, all datasets must comply with the provisions of the Federal Data Protection Act. Further details can be found in the legal notice.

16. What is an API? What are WMS and WFS and how do I use them?

An API (application programming interface) is used to integrate data directly into an application. For example, Web Map Services (WMS) and Web Feature Services (WFS) can be used to integrate geodata into applications and display them there as maps.

Using these services requires some experience of data processing. Detailed documentation on integration using API can be found on geo.admin.ch, the Confederation’s geographical information portal. The WMS and WFS services on opendata.swiss are shown as links. Clicking on the link only displays an XML representation of the service in the portal. To actually use the service, you must integrate the link into your own application.

17. Is there a place for developers, designers and other interested parties to discuss ideas, applications and the development of OGD?

In Switzerland, the association opendata.ch campaigns for the publication of data from the public authorities. To promote the use of these data, the association stages events, at which anyone interested in OGD can work on actual projects involving data from the authorities.
