Atomic Data

Protocolo Semântico e de Dados

Modular specification for sharing, modifying, and modeling graph data combining the ease of use of JSON, the connectivity of RDF (linked data), and the reliability of type-safety. A strict subset of RDF with built-in schema validation via Atomic Schema (Classes, Properties, Datatypes). Uses links (URLs) to connect pieces of data, making it easier to connect datasets even across separate machines. Extended modules cover Commits (signed state changes with version history), Agents (authentication via public/private keys), Collections (querying/filtering/sorting), Hierarchies (authorization), WebSockets (real-time updates), and file management

Protocolo Semântico e de Dados Atributos

Origens Linked Data / Semantic Web improvement (inspired by Tim Berners-Lee; takes best of Linked Data but improves with JSON compatibility, type safety, and clear consistent protocol; addresses RDF's technical complexity that limits developer adoption)
Banco de Dados Sled embedded database (file-based key-value store in AtomicServer); graph database model; full-text search via tantivy (<3ms responses); 8MB download, no runtime dependencies; <1ms median response time
Linguagem de Consulta Atomic Paths (traverse graphs via URL path segments) + Atomic Collections (querying, filtering, sorting, pagination) + full-text search with fuzzy search and operators; SPARQL-compatible via RDF interoperability
Formatos de Dados JSON-AD (Atomic Data JSON serialization — JSON where each key is a URL of an Atomic Property; ensures type-safety via Properties with datatypes, shortnames, and descriptions) + RDF (strict subset; can convert to/from RDF formats)
Edição Colaborativa em Tempo Real Supported (real-time sync via WebSockets in AtomicServer; Commits track all state changes with cryptographic signatures for audit trail and version history)
Edição de Texto Rico Yes (AtomicServer GUI includes documents, tables, and chat with rich editing; AI assistant with MCP support)
Suporte Móvel Planned (atomic-data-browser designed as web app, responsive for mobile; no dedicated native mobile app)
Suporte Web Yes (atomic-data-browser bundled with AtomicServer; features group chat, tables, documents; demo at atomicdata.dev; React and Svelte SDKs for building web apps)
Aplicativos Nativos AtomicServer (desktop/server; runs via Docker or binary; 8MB lightweight); atomic-cli command line tool
Termos Self-hosting (run own AtomicServer via Docker or binary; atomicdata.dev as public demo instance)
Fundos ~€100k (NGI DAPSI + 2 NLnet grants via NGI Zero programme)
Baseado Em RDF / Linked Data (strict subset of RDF; JSON-AD as default serialization; Atomic Schema for type-safe classes/properties/datatypes; Atomic Commits for signed state changes inspired by Git; comparison pages for RDF, Solid, JSON, IPFS, SQL, and graph databases in documentation)
Compatibilidade com a Web Semântica Full RDF compatibility (strict subset of RDF; can convert to/from RDF; designed to be easier to use than raw RDF while maintaining linked data connectivity; W3C Atomic Data Community Group)
Maturidade / Padronização do Protocolo Proprietary Open Standard (published specification at docs.atomicdata.dev; developed by Ontola/Joep Meindertsma)
Tipo de Vocabulário / Ontologia General-purpose / Graph database and linked data; Atomic Schema provides type-safe ontology with Classes, Properties, and Datatypes; built-in Ontology Editor in AtomicServer for creating and sharing custom data models
Padrão de Uso Standalone (AtomicServer as graph database + headless CMS + all-in-one workspace) + embedded (atomic-lib Rust library, @tomic/lib JavaScript library for building apps); use cases include headless CMS, personal data store, e-commerce, surveys, verifiable credentials, data catalogs, education, food labels
