We need better Open Data Interfaces
2017, October 10
Better?! Come on, you must be more precise with your feedback!A scientist
Every dataset, how small it may be, may contribute at some point to finding an answer to some question. Yet, we have a big problem. Almost nobody* is reusing the small datasets published on Open Data portals. At least, if the data would indeed be useful, we should be able to notice evidence of data reuse in our daily applications. Is this a huge fallacy for those who claim there is economic and societal value in their freshly published datasets?
For the years to come, Open Data researchers will need to prove that publishing data publicly is in the interest of both existing and new business models. I accredit the lack of adoption today to a simple cost-benefit analysis: would you reuse a dataset when it costs you more to integrate it in your system than the benefits it would give to your end-users? I know I wouldn’t.
Now that I am a postdoctoral researcher, I am in charge of leading a small research team. For the next years, our new “Linked Open Data Interfaces” (LODI) team is going to research how to lower the cost for adoption. I have already found funding to expand this team with junior researcher, and I am now looking for information/software engineers that would like to join.
* To be fair, there is some uptake, but not to the extent that data gets picked up automatically by any interface that could benefit from it. How can we advance the state of the art in data publishing, so Open Data really thrives?
What we do
We have a vision for a better world, where knowledge creates power for the many, not the few. If anyone can access public data, rather than a few with the deepest pockets, we create a more level playing field for building on top of the single and largest human knowledge base. You may recognize the slogan from the NGO Open Knowledge, with whom we work together in projects such as OASIS and open Summer of code.
We research how to create better Open Data interfaces. We define “better” as how much easier it makes the lives of reusers. Our job entails making sure the interfaces are more reliable (and thus more cost-efficient for the data publisher), interoperable, queryable and discoverable.
You can compare our Linked Open Data Interfaces team with a university hospital where a doctor does specialized consultation on the one hand, and ground breaking research on the other. On the one hand, our inspiration for research comes from real experiences in the field. We work with, among others, the Flemish government on projects to decide on the new open information architectures. In bilateral projects, organizations can hire our team for short projects to publish data in better ways. But we are also involved in longer projects, where similar data interfaces need to be studied.
More information on such projects (in Dutch): data.vlaanderen.be, Smart Flanders and Local Decisions as Linked Open Data
On the other hand, we do fundamental research. For example, with Linked Data Fragments we introduced a way to study the trade-offs on Linked Data Interfaces, we study what features of new technologies such as http/2 could be exploited for data publishing, or we are studying how to build a crawler that would be able to plan travels by public transit options world-wide.

Apply for a job at our lab
You are joining team lodi (Linked Open Data Interfaces) at the Internet and Data Lab in Ghent: a team of 5 researchers that want to see a world where knowledge creates power for the many, not the few. Your ambition is to become one of the main data architects within Flanders.
The first deadline is to send an e-mail to Pieter Colpaert with your CV and motivation letter before the 8th of November. We envision the first hire to start in January, but earlier or later is possible.
- You have a masters degree and are experienced in computer science or engineering.
- You are living in or willing to move to Belgium
- You speak Dutch and live in Flanders. This is considered a big advantage, as many projects will be in collaboration with the Flemish government. But do apply if you are able to speak English as well! We will have other projects as well, and we are hiring 3 people in total.
- The salary is fixed and depends on the years you have worked so far. We can make an estimation of a net salary if you contact us by mail.
- The research you do can lead to a PhD (although this is not a requirement).
