Building on the Open Platform
How to build on AsteriaStar as an open, research-grade data platform — the public Graph API, the JSON and JSON-LD/RDF exports, bulk downloads with verifiable checksums, and the licensing — and how it stays honest about the standards it is architecture-ready for but does not yet host.

- Platform capability
Public Graph API
A read-only, deterministic REST API over the whole knowledge graph — list and fetch entities, list relationships, search, and traverse neighbourhoods and shortest paths. Every response carries a provenance envelope (version, source, licence, attribution). No auth, no rate limits, no write endpoints.
- Platform capability
Knowledge Graph Export (JSON-LD / RDF)
The graph as JSON-LD — an RDF-compatible, SPARQL-ready document with a resolvable @id per node and relations as predicates. The linked-data foundation the SPARQL and federation layers are built to sit on.
- Platform capability
Bulk Downloads
The full graph exports offered as bulk downloads, each with a REAL byte size and SHA-256 checksum computed from the exact bytes served, plus its licence and release. No download is fabricated — the checksum can be verified against the file.
- Platform capability
Licensing Matrix
A clear matrix of the licences that apply — the platform's own CC BY-SA 4.0 for the graph and API, and the individual terms of each upstream source (NASA, ESA, IAU, and the rest) — so reuse obligations are never in doubt.
