Valueflows

Protocolo Semântico e de Dados

Vocabulary for the distributed economic networks of the next economy, to coordinate the creation, distribution, and exchange of economic resources. Implements the REA (Resource, Event, Agent) accounting ontology with additions for recipes, offers/requests, ecological accounting, and distributed protocol compatibility. Designed to support coordination both inside and between organizations (enterprise not assumed), reciprocity with or without money (money not assumed), and ecological agents as part of the economic network

Órgão de Governança None (open community governance by the ValueFlows contributor community; W3C-adjacent but not on a formal W3C track)
País International
Ano de Início 2014
Stack Implementation-dependent (vocabulary only — defines data model, not runtime); reference implementations: hREA (Rust/Holochain + JavaScript GraphQL); Bonfire (Elixir/Phoenix + ActivityPub); Basis Project (Rust, auto-generated from OWL file)
Financiamento Community-driven; EU Reflow project funded Dyne's Valueflows development (including EU Digital Product Passport); NLnet funding for related projects

Protocolo Semântico e de Dados Atributos

Origens Economic coordination / REA accounting (evolved from REA ontology through Sensorica's NRP software, Open Value Networks, FreedomCoop's OCP; addresses limitations of conventional debit/credit accounting by modeling real-world economic activity directly)
Banco de Dados Implementation-dependent (hREA uses Holochain DHT; Bonfire uses PostgreSQL; vocabulary itself is storage-agnostic)
Linguagem de Consulta SPARQL (for RDF implementations); GraphQL (primary API specification for implementations; hREA and Bonfire both expose ValueFlows GraphQL API enabling cross-project UI compatibility)
Formatos de Dados RDF (Turtle, JSON-LD; linked open data namespace at w3id.org) + GraphQL schemas + JSON-Schema reference; vocabulary supports both RDF-based and non-RDF-based usage
Edição Colaborativa em Tempo Real N/A (vocabulary defines economic data model; real-time coordination handled by implementations)
Edição de Texto Rico N/A (vocabulary only)
Suporte Móvel N/A (vocabulary only; implementations may have mobile support)
Suporte Web N/A (vocabulary only; implementations like Bonfire and hREA provide web interfaces)
Aplicativos Nativos N/A (vocabulary only)
Termos Free open vocabulary (CC0/Public Domain)
Fundos N/A (core vocabulary is volunteer-driven; implementations separately funded)
Baseado Em REA (Resource-Event-Agent) accounting model (William McCarthy, 1982); extensions for recipes, offers/requests (Intents), ecological accounting, process flows (IPO: Input-Process-Output chains), agreements/exchanges; ActivityPub federation via Bonfire (FEP proposals for Federated Marketplace, Federated Work Coordination, To-do's)
Compatibilidade com a Web Semântica Full RDF compliance (core design principle; linked open data namespace; Turtle and JSON-LD serialization; UML diagrams; designed to support both RDF-based and non-RDF-based use)
Maturidade / Padronização do Protocolo Community Standard (vocabulary specification developed by international community; W3C-adjacent but not formal W3C track)
Tipo de Vocabulário / Ontologia Economic flows / Resource, Event, and Agent coordination; covers planning (Intents, Commitments, Proposals), observation (Economic Events, Economic Resources), recipes (RecipeProcess, RecipeFlow), agents (persons, organizations, ecological agents), processes (IPO chains), exchanges, and agreements
Padrão de Uso Embedded in other protocols and platforms (used by hREA on Holochain, Bonfire on ActivityPub/Fediverse, Dyne's Reflow/Interfacer for EU Digital Product Passport, Carbon Farm Network/NY Textile Lab for supply chains, Sensorica for open value networks, LearnDeep for fablab materials sharing, Basis Project for ecological production, Code A for climate accounting education, Weather Makers for ecosystem restoration planning)
