Ontologies × open data
Ontologies at work.
Three applications, one conviction: when open data is described by a shared ontology, you can explore it, question it and build on it. This site is the hub for these projects, and for the creative, open ones that will follow.

LOMO
EU law, obligation by obligation.
Legal obligations are extracted from EUR-Lex texts, described with the LOMO ontology, then reviewed, searched and queried: who must do what, and under which article.
- LOMO
- EUR-Lex
- ELI
- SPARQL
DOREMUS
Music as a graph.
Catalogue and discover works, concerts and recordings with the DOREMUS ontology: search by casting, timelines, networks and explained recommendations, on the open data of data.doremus.org.
- DOREMUS
- FRBRoo
- CIDOC-CRM
- SHACL
3D Codex
Manuscripts in three dimensions.
Turn a restored codex around, open its binding piece by piece, read its pages, then ask the book your questions. Conservation described with CIDOC-CRM becomes an object you can handle.

Why ontologies?
A shared meaning
An ontology says what things are and how they relate. Data stops being columns and becomes facts you can connect.
Open data
Legal texts, music catalogues, written heritage: the material already exists, published by institutions. What remains is to make it usable.
Answers you can check
Every result points back to its source: an article, a record, a folio. AI helps to extract and to ask, the graph keeps the evidence.
What comes next
A hub for creative, open projects.
These three applications are a start. Other projects will join them: same method, other fields.
