“Join the drive for a new open European infrastructure for web search” I CORDIS

The Community Research and Development Information Service (CORDIS) is the European Commission’s primary source of results from the projects funded by the EU’s framework programmes for research and innovation, from FP1 to Horizon Europe.

OWS.EU – as Horizon Europe project – is currently calling on third-parties to contribute innovations and infrastructure to help further develop the Open Web Index. The Calls have been published on the CORDIS website and they are closing on April 4th 17 CET:


“People to Watch: Dieter Kranzlmüller” I HPCwire

“The OpenWebSearch.eu project and the Open Search Foundation — both founded and based in Europe — come from a background of open source, open data, open access, and open science. These values have always resonated with my academic career, but of course also with LRZ as an institution“, says Dieter Kranzlmüller – Chair of the Board of Directors, Leibniz Supercomputing Centre (LRZ) – in a recent interview on HPCwire. Being named a “person to watch in 2024“ by the renowned computer-centred news platform, he was asked to share about LRZ‘s role in the OpenWebSearch.eu project. As one of the 14 consortium partners LRZ plays a key role in providing a stable infrastructure as one of Germany‘s top notch data centres.

„It takes plenty of little Davids“ I Agoratalk

The OpenWebSearch.eu project was mentioned in a recent Agoratalk podcast episode featuring Christine Plote – Chairwoman at the Open Search Foundation which is one of the fourteen OWS.EU consortium entities.

The title of the episode was “Ethics in the digital space. Alternatives instead of regulation on the net”. Together with podcast hosts Daniel Höche and Olivier Blanchard, Christine discussed the current digital landscape including ethical and societal challenges. The conversation also dove into the rather monopolistic search engine market that capitalizes on private data and shapes filter bubbles with huge, yet often invisible societal consequences.

Christine Plote shared insights on the motivation behind OWS.EU, explaining why it takes many “small Davids“ to build true alternatives to the established commerce-driven web search giants.

New Calls for Third-party Proposals and new Funding Round to be Launched in February 2024

OpenWebSearch.eu to launch open calls #2 and #3 soon, offering funding and onboarding to third-parties

After Call #1 in March 2023 and the resulting successful onboarding of six third-party partners in November 2023, the OpenWebSearch.EU will call for proposals again in February: Calls #2 and #3 will invite researchers, innovators and data centres to submit their applications to participate in the Open Web Search mission and receive funding for their project ideas. The calls will launch in February, applications will be accepted until April 2024.

ows.eu Call #2:
Applications of an Open Web Index

Call #2 will particularly ask for proposals for applications of the Open Web Index. The Open WebSearch.eu project will provide access to pre-processed and indexed data in the terabyte range. Also it will deliver continuous, daily updates until the end of the project. Successful applicants should use and exploit the data provided in innovative applications scenarios or research topics.

Under this call, applicants will be able to apply for funding of between EUR 50,000.00 and EUR 100,000.00 for a funding period of up to 12 months.

ows.eu Call #3:
Onboarding of Data Centres

Call #3 will address computing and data centers to join the OpenWebSearch.eu network of infrastructure organisations and hosting parts of the OWSAI infrastructure. The ows.eu consortium aims to on-board data centers as a proof-of-concept for the developed technology and engage in discussions on creating a sustainable future infrastructure. Called will be universities, public infrastructure providers, data centres, companies (e.g., cloud providers) or research teams with a well established infrastructure. Applicants should be capable of providing a significant extension to the current OpenWebSearch.eu data and compute infrastructure, and engaging in relevant infrastructure-oriented R&D activities.

Under call#3, applicants can request funding between 100.000,00 and 150.000,00 EUR for a funding period of up to 12 months. Major cost categories can include infrastructure costs, other costs and human resources.


More information on the calls and the call application packages will be launched in February 2024 on the third-party call landingpage.

The open calls are part of the OpenWebSearch.eu community programme, aiming to integrating new third-party project teams into the OpenWebSearch.eu landscape and future activities for sustainable Research and Development. Therefore, the candidate third-party projects should probe the closely related topics addressed in the project and should aim at widening and enriching the existing R&D activities as well as suggesting new ones which are complementary to the project goals and aims. Ideally, the project results should be integrated with the OpenWebSearch.eu infrastructure.

“Towards an unbiased digital world“ I CERN Courier

“We don’t want to copy what others are doing.“ – Interview with Andreas Wagner of ows.eu project partner CERN

2024 marks the second year for the EU funded project OpenWebSearch.eu – a project that aims to develop and create a European Open Web Index to ensure European sovereignty in the digital arena. Among the 14 project partners is CERN, the European Laboratory for Particle Physics in Geneva. Andreas Wagner of the CERN IT Department and responsible for the OWS.EU project lead within CERN, was interviewed about the ambitious project in CERN Courier – the renowned monthly magazine for high-energy physics.

In the interview he shares about the collaborative approach of the project in building a foundation for less biased, transparent and open access to information in the digital world. Read about the current status of the project, including first crawling activities, as well as an outlook on how the project could move ahead with regard to aspects such as funding, navigating through legal frameworks and establishing ethical rules of conduct and curation.

“Ethical, open and non-commercial: the Open Web Search project is designed to provide Europe with the right alternative to existing search engines” | CERN news

Our project partner CERN featured OWS.EU in their news section. Very readworthy article about the Open Web Search project and its goal of securing Europe’s contributing to Europe’s digital sovereignty as well as promoting an open human-centered search engine market.

“Together with the other partners, we have started by simply discussing possible ways of building a new neutral indexing system,” explains ows.eu team member Andreas Wagner from CERN. “Although the system is still very preliminary, running the it on our own set of webpages at CERN has proved useful as it has allowed us to learn critical things about our own internal search engine. In other words, the project will also help CERN to improve its own search capabilities and will provide an open science search function across CERN’s multiple information repositories.”

Common Goals with Common Crawl

OWS.EU constantly thrives to move forward with more transparent, self-determined web search. With the aim to build a Europe-based Open Web Index, choosing trustworthy, powerful crawling partners is key. Common Crawl is one such dedicated and renowned partner. It is therefore an honor to be featured on their website in the official partners section.

Common Crawl is not only a major resource for web-innovations, but also an inspiring partner. We are particularly looking forward to co-operating on license-aware crawling and to integrate their crawls into our open web index,“ says Michael Granitzer, OWS.EU’s principal investigator.

The Common Crawl Foundation is an NGO that crawls the web and freely provides its archives and datasets to the public. Its mission: to democratize Open Web Search, “enabling free access to web crawl data encourages collaboration and interdisciplinary research, as organizations, academia, and non-profits can work together to address complex challenges.” The non-profit has significantly expanded its core team throughout the last two years and is continually growing.

We are proud to be an early partner, sharing a similar vision.
