The 19th legislature of the Chamber and the Senate as an RDF graph. Members of Parliament, groups, acts, sittings, speeches and votes, linked to each other and to EuroVoc topics. It is the same graph that Stenografo, Fascicoli and Scranno use.
In the graph, as of 16 October 2026
Who they are. In the Chamber, 399 deputies in office and 16 who left during the legislature. In the Senate, 205 senators in office, 5 of them for life, and 7 no longer in office, including Giorgio Napolitano, senator for life, who died in 2023. The graph also has 23 members of the Government without a seat in Parliament.
Sources: open data of the Chamber (dati.camera.it) and the Senate (dati.senato.it), EuroVoc thesaurus. The figures update with the graph, after every new sitting.
How it is designed
People, acts, sittings, speeches and votes have a stable URI. For people we use the official one: dati.camera.it for deputies, dati.senato.it for senators. Anyone who already has that data links it to ours without conversion tables.
We use vocabularies that already exist. A program that knows W3C ORG understands our groups; one that knows EuroVoc reads the topics of the acts in 24 languages.
Every piece of information is a triple: subject, relation, object. Triples can be counted, filtered and joined with other data. The export has 863,834.

Abbreviations of the vocabularies used. All except pro: already exist and are maintained by others.
The URI is the one of the Chamber's official profile. For senators it is the one on dati.senato.it. The same address works in any other dataset that uses it.
A person for anyone using FOAF, and a deputy in the Chamber's open data vocabulary.
An organisation in the W3C ORG sense, the same model used for parties, public bodies and companies.
Links person and group with a start date, and an end date when there is one. If a deputy changes group, a new membership is created: the history stays in the graph.

Vocabularies
| In the graph | Vocabulary | What it allows |
|---|---|---|
| Deputy | ocd:deputato, foaf:Person | The Chamber's own official record, reusable anywhere. For senators, the one on dati.senato.it. |
| Parliamentary group, committee | org:Organization | The W3C model for organisations. |
| Membership of a group | org:Membership | Start and end: changes of group stay on record. |
| Topic of an act | EuroVoc, via SKOS | The same topics in 24 languages. |
| Sitting, debate, speech | The international standard for parliamentary records | A structure other parliaments already use. |
| Roll call and individual vote | ocd | The Chamber's open data vocabulary. |
| Provenance | prov | Every build states when it was made and from which sources. |

The graph in Turtle: people, groups, committees, acts, EuroVoc topics, sittings, debates and speeches with the full text.
Individual votes
In a separate file, because it is the largest: the vote of every member of Parliament in every roll call.
emeierkeio/parliamentrag-leg19
The data of the 19th legislature in table form, for people who work with pandas, R or a spreadsheet rather than RDF.
parliamentrag-iswc / build
The code that builds the graph from the open data of the Chamber and the Senate. Anyone can rebuild it from scratch and compare.
The data is released under the CC BY-SA 4.0 licence. You can copy, modify and redistribute it, commercially too, if you credit the source and use the same licence. The sources are the open data of the Chamber (CC BY-SA 4.0) and the Senate (CC BY 3.0).
On Zenodo we publish a snapshot at major milestones, not at every update. The graph used by the systems is more recent than the latest snapshot.
The export does not contain the embeddings, users' conversations or summaries written by AI. Only public data and its relations.
Query it
An MCP server exposes the graph to the AI assistants that support it. The assistant searches the speeches, opens a debate, reads a vote, and every result links to the record.
