Semantic tooling for institutions, researchers, and curious individuals.
We build open-source infrastructure for structured knowledge — schema-driven applications, local-first knowledge graphs, and tools that make linked data accessible beyond the specialist.
Define your data model once. Everything else follows.
One LinkML schema drives forms, filterable tables, detail views, CLI tools, REST APIs, and documentation — against any backend (in-browser SPARQL, Prisma/SQL, REST, or local Oxigraph WASM).
→ Concept Book · Storybook · TypeDoc API
Your data lives in your browser. Oxigraph runs as a WebAssembly worker; authority sources (Wikidata, GND, OpenStreetMap, DBpedia) integrate through a declarative mapping layer. No server required to start.
The same infrastructure that powers institutional catalogues works equally well as a personal knowledge base — notes, entities, relationships, all queryable via SPARQL from day one.
The long arc of this work aims at a single thing: making the semantic web's expressive power usable by domain experts, librarians, archivists, and individuals — not just ontology engineers.
