Deliberation Interoperability Project

Protocolo Semántico y de Datos

A Rust-based common data model and set of platform adaptors for deliberative-democracy tools, from the Metagov research collective (metagov/ontology). Core entities: Person, Statement (roles: Question, Belief, Fact, Evidence, Refutation, Summary, Proposal, Decision), Project, Phase, Reaction, Collection, Event; decision mechanisms include ranked-choice and quadratic voting. Exports to three target formats — RDF/JSON-LD (semantic web/research publication), AT Protocol lexicons (Bluesky/ATproto integration), and JSON Schema (API validation/OpenAPI) — rather than depending on any single transport substrate. Ships platform adaptors for Polis (opinion clustering), HeyForm (forms/polls), and Talk to the City (API-based report generation). Its data-model and adaptor structure appears extracted from CrownShy's Comhairle (github.com/crownshy/comhairle, AGPL-3.0, 1,518 commits) — a real architectural lineage, though Comhairle itself is a conventional AWS/K8s deliberation web platform with no inter-instance protocol of its own and is not itself part of this matrix. Distinct from, and complementary to, this project's existing Decentralized Deliberation Stack (DDS) entry: DDS is a W3C Community Group protocol/interface spec (Plan/Collect/Analyze) built specifically on AT Protocol as a required transport layer, whereas this project defines a transport-agnostic data model with ATProto lexicons as only one of several optional export targets, plus concrete adaptors to existing tools rather than new interfaces.

Protocolo Semántico y de Datos Atributos

Orígenes Deliberative democracy / civic tech interoperability — motivated by the same tool-siloing problem DDS addresses (data from one deliberation tool can't be read by another), approached via a common data model + adaptors rather than a new transport protocol
Base de Datos N/A — defines a data model and exporters, not storage; data lives wherever the exporting platform or ATProto lexicon target stores it
Lenguaje de Consulta N/A
Formatos de Datos RDF/JSON-LD; AT Protocol Lexicon schemas; JSON Schema — three parallel export targets for the same underlying data model
Edición Colaborativa en Vivo N/A
Edición de Texto Enriquecido N/A
Soporte Móvil N/A (data model/library, not an end-user app)
Soporte Web N/A directly; consumed by web-based adaptor targets (Polis, HeyForm, Talk to the City)
Aplicaciones Nativas N/A
Términos Free / open (license intent stated as MPL-2.0; see license nuance above)
Fondos Unknown
Basado En Deliberation-tool data drawn from Polis, HeyForm, and Talk to the City (adaptor targets); AT Protocol Lexicon spec (one of three export targets); data-model and adaptor structure appears extracted from CrownShy's Comhairle (github.com/crownshy/comhairle, AGPL-3.0)
Compatibilidad con la Web Semántica Yes — RDF/JSON-LD is one of the three first-class export targets, explicitly for semantic-web/research-publication use
Madurez del Protocolo / Estandarización Pre-standard, single-repository research project; no formal standards-body involvement; overlaps in subject matter with the W3C Community Group-backed DDS entry but pursues a different (data-model-first, multi-target-export) approach
Tipo de Vocabulario / Ontología Deliberation-domain ontology — Person / Statement (8 roles: Question, Belief, Fact, Evidence, Refutation, Summary, Proposal, Decision) / Project / Phase / Reaction / Collection / Event, plus ranked-choice and quadratic-voting decision mechanisms
Patrón de Uso Library/exporter consumed by adaptors for existing deliberation platforms (Polis, HeyForm, Talk to the City), not a standalone end-user tool
