How to use data
1. Find data
How did my backyard look like 80 years ago? What municipal decisions are currently under debate? How much of my tax contributions have been used in the development of this web service? Search for interesting data in the HRI data catalogue – or give us your suggestions for opening data that genuinely interests you. Think about combining different datasets to create something new and intriguing!
For example: The cities of Helsinki, Espoo, Vantaa and Kauniainen published their financial statements with hundreds of thousands of rows of data – what would you do with this data? Perhaps combine them with the map of regional public services?
2. Create or find an idea for an app
How to utilise interesting data? You can find a useful overview of existing apps, web services, visualizations and mobile services in the HRI app gallery. You can also browse the international catalogue of apps for ideas and make a localized version for your own city. If you have a good idea but lack the time or skills to develop your concept further; share it with others here!
For example: The Apps4Finland competition has a category solely dedicated for app ideas. In the 2013 competition, Faris Alsuhail’s and Tuomo Leino’s Kalamiäs (“Fisherman”) concept won in the “Inspire” category.
3. Build your app
Breathe life into data: visualize it, conduct academic research, build a web service, or engage in data journalism. Open data has a variety of tools for different topics and areas of interest. You can ask for help from experienced data users in the HRI discussion forum. According to research the majority of developers building apps with open data are researchers, freelancers and private application developers. Also, there are a small number of firms engaging with open data as they have spotted its potential.
Successful examples of apps created with open data are the winners of the Apps4Finland competition: ParkMan (formerly known as Parkkinappi) and BlindSquare which are both commercially available internationally.
4. Publish & share your app on the web
Don’t keep your app just for yourself. Value for your visualization or web service is only created after it is being used. Publishing your app on your website is the first step. Next, add your creation to the HRI app gallery, engage in internationally organized open data app competitions, and promote your work through social media.
For example: Journalists across the world are very excited about data journalism. The British Guardian is a forerunner in this emerging field. Take a look at their data journalism approach on their data blog. Helsingin Sanomat has also outlined its stance towards open data in their Next-blog.
5. Gather feedback & interact
Services using open data provide users with new experiences and information. A great newspaper article can bring numbers and data to life, a nifty or ingenious mobile service can make your everyday life easier. Open data apps have the potential to facilitate social discussions and to increase the transparency and reach of democracy.
For example: The Kansan muisti service (tr. “citizens’ memory”) offers the possibility to easily follow the speaking order of politicians and to follow the outcomes of municipal votes. Essentially, it offers the opportunity to track the progress of election promises. Additionally, the Päätökset service (tr. “decisions”) promises to make the City of Helsinki’s decision-making process available for everyone in a transparent and easy manner.
