What is AHORN?

AHORN is a repository of higher-order network datasets, providing researchers with access to resources for benchmarking, testing algorithms, and exploring new questions in network science.

It is built around discoverability and reproducibility: each dataset page combines structured metadata, source links, download attachments, and citation information in one place.

Work in Progress

AHORN was introduced at the Higher Order Opportunities and Challenges workshop in Aachen from August 11 to August 13, 2025. The repository is still expanding, and community contributions remain a central part of improving the collection and the overall user experience.
