Knowledge first
The knowledge graph is the product. Every page, explorer, and future app reads from it.
Stable identifiers
Every entity has a permanent type:slug id (e.g. star:sirius) that never changes or recycles.
Open standards
JSON and JSON-LD today; RDF/SPARQL-ready, with GraphQL and REST contracts documented.
Machine- & human-readable
Structured for search engines, LLMs, researchers, and developers — and clear for people.
Versioned
Graph, schema, and dataset versions for long-term compatibility.
Sourced, never invented
Facts cite authoritative sources; nothing is fabricated, including datasets and downloads.
