Open Data service can be used by everyone interested in open data – journalists, software developers and ordinary people alike.
Our service is divided into publishers, datasets and showcases. Datasets are the actual open data. Each dataset belongs to a publisher, an organisation. Our showcase gallery contains a variety of examples on how open data can be used in practice.
You can search, browse, use and download the data available on our service for your own use even if you do not have user account. The advanced search is an easy way to find information about topics that you are interested in.
What are datasets?
A dataset is composed of metadata, that is, data that describes its content in more detail, and of one or more data resources.
Our service provides a growing collection of datasets on different topics. You can browse all the datasets in our service or search for datasets related to themes that you are interested in. For example, you can find out which names have been the most popular ones in Finland, what the state has spent money on and the current municipal divisions.
Data resources contain the actual data of the dataset.
For example, resources may contain:
- Similar data from different years: Data from the OpenProcurement.fi service contains a separate data resource for each year.
- Data that has been divided into sections: In the Digital and Population Data Services Agency’s dataset on Finnish names, first and last names have been divided into separate files.
- The same data in different file formats: The numbers of people using public transport in Helsinki are available both as a CSV table and an API. An API is often used to publish constantly changing data.
You can download the data resource of your choice for your own use by selecting Download or Open next to the resource.
The license defines the terms and conditions under which the opened data may be used. Open data datasets are all licensed under an open licence, which means that anyone can use the data freely for any purpose.
We recommend the following licences for open data datasets: Creative Commons BY 4.0 or Creative Commons CC0 1.0. The main difference between the two licences is that data under the CC0 1.0 licence can be used without mentioning the original source of the data, whereas the CC BY 4.0 licence requires the original source to be mentioned when the data is used. The majority of the datasets found on our service have been licensed under one of these two licences.
What are showcases?
On our website, you can also find showcases that use open data. They are examples of what open data can be used for and how we can all benefit from using it. Showcases include different mobile applications, visualisations and websites that use open data.
Open data is useful in many different areas. In our gallery, you will find applications that make getting around easier, visualisations of financial matters and examples of how population information can be used.
Open data makes it possible to create a better-functioning and more equal society for all of us.
Accessible navigator — Blindsquare
Blindsquare on avoimeen dataan perustuva sovellus, joka helpottaa näkövammaisten liikkumista. Sovellus kuvailee lähiympäristöä ja sen kohteita ääneen käyttäjälle. Se kertoo esimerkiksi lähistön kiinnostavista kohteista ja ilmoittaa lähestyvistä risteyksistä. Blindsquarea voi käyttää myös ääniohjauksella.
If you have created a showcase that uses open data and would like to add it to our website, let us know about it. You can also tell us about showcases other than your own. We will contact the developer and add the showcase to our service.
