OWS.EU Partner in Focus: SUMA-EV
SUMA-EV is the next partner we are introducing. The German non-profit organization is comitted to promoting free access to knowledge and protecting online privacy. It pursues these goals through conferences, funding and support of promising projects, and performing talks at educational institutions.
A central part of its work is operating MetaGer, a privacy-focused meta search engine that has been running since 1996 in cooperation with the University of Hanover. As a partner of OWS.eu, Suma-ev is a driving force behind the Open Web Index movement and played a key role in supporting the launch of the Open Search Foundation in 2020.
Phil Höfer, the organization’s technical counselor, contributes together with his team their extensive experience in running a large meta search engine and in processing search results from index-based search systems.
Thanks to Phil for taking the time to share your insights with us.

Please describe your organization’s tasks in the project. What is your field of expertise that you bring to the project?
Phil: SUMA-EV has been running search engine projects for multiple decades and has been working towards an Open Web Index during those years. We aim to further help the transformation of the OWI from research prototype to public amenity by focusing on adoption and application support.
How is the project progressing? Which major milestones did you achieve?
Phil: As the project nears its conclusion, we’re glad to see the pieces coming together. We’ve succeeded in integrating the OWI data into our infrastructure and built an independent functional open-source implementation of the higher search stack elements.
What are the challenges you have been facing (regarding your tasks)?
Phil: Developing applications against a changing data format was one of the main challenges. The same is true of missing documentation. These are common challenges when–so to say–building the rocket while launching it.
Which milestones do you plan to achieve in the remaining months?
Phil: My hope is that we can present a public-facing service demonstrating the ease of integration with OWS data before the end of the project. A part of that relies on fixing remaining compatibility bugs in MOSAIC and publishing our framework for working with OWS index data.
What makes the OWS project special to you?
Phil: Unlike with the failed Quaero project, this is the first time Europe has decided to explicitly push for sovereignty in web search and web data analysis. Only through this we can ensure availability and accessibility of web search as a public ressource.
Do you already have plans for the time after the project ends?
Phil: For us, the end of the project is only the beginning. While the question of how to keep the index going is most important, we also strongly believe that the index is useless if it isn’t being used. Thus, we plan to provide tooling and infrastructure to build search-related projects on top of OWS index data.
Thank you for the interview!
