Eviota Case Study

Music Eviota is strategically built on a foundation of proprietary components that intricately link various open-source software components. Our selection of open-source software components is guided by their high TLR level, instilling confidence in the system's reliability.

This public repository shows the public elements.

This is a public repository documenting a methodological case study developed within the Open Music Europe (OpenMusE) project. The master repository is held at dataobservatory-eu/eviota_case_study.

Folders

• root - The individual pages of the methodological case study files in qmd files.

• The main open source component is the iotables software library that is open source and has its own product website. It was released following peer-review.

• The proprietary software components are held in the Eviota organisation's private repositories. A high-level system description was deposited with a public notary for IP protection.

• The eviota-methodology private folder contains a detailed methodological description, part of which remains proprietary, and part will be sent for scientific peer-review.

• The eviotaR repository contains proprietary code that complements the iotables](https://iotables.dataobservatory.eu/) peer-reviewed code base.

• The glossbuilder and the filmledgerimport contains scripts to improve the natural language based verification of unmatched items in English, Hungarian and Italian.

• In a music environment, the Eviota system is designed to operate within a federated data-sharing architecture such as the Open Music Observatory's Society and Sustainability pillar, which provides shared semantics, identifiers, and governance across public and private data layers.

• quivalent architectural principles are applied in related implementations, such as the Hungarian Motion Picture Data Space (MMAT) for film and audiovisual production.

This repository follows Open Policy Analysis (OPA) principles by preserving context, provenance, and consultation history at the level of individual artefacts. Because Eviota constitutes a "sensitive", IP protected output, the OPA applicability is limited here compared to our other work under the OpenMusE research and innovation action.

Status, scope, and responsibility

This repository documents a case-study–level subtask contribution within the Open Music Europe (OpenMusE) project. It is provided to document work performed and to support transparency, consultation, and potential reuse.

This project has received funding from the European Union’s Horizon Europe programme under Grant Agreement No. 101095295. The views expressed are those of the authors only and do not necessarily reflect those of the European Commission or its agencies.

Provenance and versioning

This repository preserves an authoritative, time-stamped record of work carried out by Reprex within the Open Music Europe (OpenMusE) Horizon Europe action (Grant Agreement No. 101095295).

The contents reflect the state of the work as prepared and handed over by the contributing partner. They do not necessarily reflect subsequent editorial consolidation, internal approval workflows, or the final versions submitted to the European Commission.

This repository is maintained in line with the Open Policy Analysis (OPA) principles of transparency, reproducibility, and traceable provenance. It exists to ensure that analytical methods, assumptions, and implementation artefacts can be independently inspected and audited if needed.

Scope and limits

• This repository contains methodological, technical, and illustrative materials related to the Eviota case study.
• It does not constitute the main project output for the relevant work package or deliverable.
• Integration of these materials into project-level deliverables, reports, or policy outputs depends on coordination decisions and inputs beyond the scope of this repository.

Role in the project

• Reprex’s role in this context is that of an innovation and data engineering partner, focusing on system design, data governance, and infrastructure components.

• Research design, data collection, and empirical validation activities are shared across designated partners as defined in the Grant Agreement, with Reprex contributing innovation, data engineering, and infrastructure components within this division of roles.

Status

• The materials are provided as-is.

The materials reflect the state of work reached under real-world constraints of timing, data sensitivity, and inter-package dependencies.
