The Polifonia registry of musical resources on the Web is https://w3id.org/musow
The previous version of musoW 1.0 is available at https://musow.kmi.open.ac.uk/.
This repository hosts the initial dataset of the registry (a fork of musoW 1.0). New data and final application are available at https://github.com/polifonia-project/registry_app.
==== From musoW 1.0
musoW is a survey on musical data available on the web and a RDF dataset including results of the survey. Here you can find the script to generate the RDF dataset from the managed CSV and several SPARQL queries.
The musoW RDF dataset can be queried at https://data.open.ac.uk/sparql. Here an example resource for starting browsing the dataset: MIDI Linked Dataset. We also published a RESTful API to reproduce results.
The following selection of SPARQL queries is meant to be a useful guide to the user who wants to discover musical data available on the web and how to reuse it!
- General queries
- Catalogs
- Digital libraries and repositories
- Datasets
- Linked Open Datasets
- Digital editions
- Services and Softwares
- Schemas and ontologies
- Formats
- About symbolic notation
The following examples show an overview of resources gathered and described in musoW survey.

We considere digital libraries as repositories of heterogeneous materials, meaning that different cultural objects are described - e.g. books, photographs, artworks, music scores. While repositories gather materials about one type of object, also providing different media (e.g. digitized scores, audio files, trascriptions of melody).
