Project Background
The Open Music Observatory (OMO) is an operational, federated European observatory infrastructure. It connects national institutions, rights organisations, research partners, and cultural heritage bodies through working data-sharing modules, including a fully functioning Slovak national node supported by signed agreements. The system runs in production and supports real governance, research, and industry use cases.
It is not a passive observation point, but an active data infrastructure that continuously records, organises, and activates music data. It enables national satellite accounts, valuation and benchmarking models, market share measurement, metadata repair, and the reactivation of out-of-circulation repertoire.
Following the European Interoperability Framework, the Observatory is integrated with the EU Open Data Portal, Europeana, OpenAIRE and other scientific networks, and other networked infrastructures. It operates under a European model of data sovereignty, respecting GDPR, copyright law, and responsible AI principles.
Designed as a permanent, open platform for a future European Music Observatory, it enables enhanced cooperation across public authorities, rights organisations, cultural institutions, researchers, and industry — connecting distributed music data without forcing centralisation or redistributing rights.
The Open Music Observatory builds on earlier European initiatives in music data integration and policy analysis, from the CEEMID project to later validation and prototyping in innovation programmes such as the Yes!Delft AI & Blockchain Incubator and the JUMP Music Market Accelerator. As background intellectual property of Reprex, it was further developed within Open Music Europe (OpenMusE), a Horizon Europe Research and Innovation Action (Grant Agreement No. 101095295), focused on governance, technical readiness, and policy-relevant data.

The Federated Data Sharing Spaces
The Open Music Observatory is built from four interoperable, federated data-sharing spaces. These demonstrate how music data can be governed responsibly at supranational, national, regional, and sub-national levels.

Finno-Ugric Data Sharing Space
A module demonstrating how minoritised and endangered ethnolinguistic communities (e.g., Livonian, Karelian, Sámi, Mari) can regain stewardship over their heritage materials. It serves as a subsidiarity example: empowering regional identity groups to curate and present their own music data.
Slovak Comprehensive Music Database
A national module developed with the National Library of Slovakia, SOZA, the Slovak Music Information Centre (IAMIC/IAML), and the Music Fund. It demonstrates how national institutions can coordinate a shared, well-governed infrastructure, supporting many policy goals described in the CITF report and the European Parliament resolution.
Hungarian Music Database
A developing module that demonstrates how countries without pre-existing shared music-data ecosystems can adopt the Observatory’s federated model. It focuses on folkloric collections, heritage archives, and post-socialist materials with metadata repair needs.
Open Music Observatory Core Module
The supranational module that aggregates European-level datasets, studies, indicators, and data from countries not yet operating a full national node. It provides a cross-European view of musical diversity, circulation, creation, and economic and cultural value.
