FOSS4G Key-note

Ton Zijlstra

The open source community is well placed to bring ‘ethics by design’ to the rest of the geo-sector.

At the 2016 edition in Bonn, Germany, of the annual FOSS4G conference “Building Bridges”, Ton Zijlstra gave a key-note titled “Openness, the bridge towards societal impact“. The short address for this page, for easy sharing, is: https://grnl.eu/foss4g

In my talk I outlined that it is often hard to see the real impact of open data.

Firstly, because it takes a lot of effort to map out all the network effects, for instance when doing micro-economic studies like we did for ESA or when you need to look for many small and varied impacts, both socially and economically. This is especially true if you take a ‘publish and it will happen’ approach. Spotting impact becomes much easier if you already know what type of impact you actually want to achieve and then publish data sets you think may enable other stakeholders to create such impact. Around real issues, in real contexts, it is much easier to spot real impact of publishing and re-using open data. It does require that the published data is serious, as serious as the issues. It also requires openness: that is what brings new stakeholders into play, and creates new perspectives towards agency so that impact results. Openness needs to be vigorously defended because of it. And the FOSS4G community is well suited to do that, as openness is part of their value set.

Secondly, because impact often results from combinations of data sets, and the current reality is that data provision is mostly much too fragmented to allow interesting combinations. Some of the specific data sets, or the right timeframe or geographic scope might be missing, making interesting re-uses impossible.
Emerging national data infrastructures, such as the Danish and the Dutch have been creating, are a good fix for this. They combine several core government data sets into a system and open it up as much as possible. Think of cadastral records, maps, persons, companies, adresses and buildings.
Geo data is at the heart of all this (maps, addresses, buildings, plots, objects), and it turns it into the linking pin for many re-uses where otherwise diverse data sets are combined.

Because of geo-data being the linking pin, the role of geo-data is shifting. First of all it puts geo-data in the very heart of every privacy discussion around open data. Combinations of data sets quickly can become privacy issues, with geo-data being the combinator. Privacy and other ethical questions arise even more now that geo-data is no longer about relatively static maps, but where sensors are making many more objects as well as human beings objects on the map in real time.
At the same time geo-data is becoming less visible in these combinations. ‘The map’ is not neccessarily a significant part of the result of combining data sets, just a catalyst on the way to get there. Will geo-data be a neutral ingredient, or will it be an ingredient with a strong attitude? An attitude that aims to actively promulgate ethical choices, not just concerning privacy, but also concerning what are statistically responsible combinations, and what are and are not legal steps in getting to an in itself legal result again? As with defending openness itself, the FOSS4G community is in a good position to push the ethical questions forward in the geo community as well as find ways of incorporating them directly in the tools they build and use.
