- 26-06-09 If it appears that some parts are becoming safer than others, resources can be moved from one to the other. Statistical data provides insights into why areas are becoming safer while others are not. There is a lot of data on safety, primarily coming from surveys and operational databases. Problem: maintained by many different organisations (Statistics Neth, Just, Internal Affairs (Police) Policy makers have to put in a lot of effort to get the data they need. They have to phone, email people, who have to make time to find what they need. They might not be there, wait for people to return calls. Often weeks go by. We developed a tool that does all this. It collects the data they need in their day-to-day work to that they have it ready when they need it. It is extensible and easily updatable. It also contains what we call “contextual data”, data that is not about safety itself, but still related in some way. Like demographics.

- 26-06-09 When we started out, we did a number of workshops with our intended users, where we demoed prototypes of the interface and asked for feedback. Some 800 indicators from some thirty sources from a dozen organisations. Privacy. – small numbers – personal accounts, logged: mandatory by law. But we also came up with our own list of requirements. We have to maintain this, so it had to be extensible and easy to update. That means that we needed to be able to connect every imaginable source, whatever its specs. Also: meta data. Exensive information about what numbers mean, where they come from, what methods used, etc.
