Federation & the Virtual Observatory

Linked-data IRIs

Every entity already carries a resolvable IRI in the JSON-LD export, the foundation for federating the graph with other linked-data sources. A published federation manifest and cross-dataset link set are architecture-ready.

Resolvable IRIs exist in the JSON-LD; a formal federation manifest and external owl:sameAs link set are architecture-ready, not yet published.

IVOA TAP / ADQL

An interface prepared for the International Virtual Observatory Alliance protocols — a TAP service answering ADQL queries over the tabular catalogues (stars, deep-sky, exoplanets). The catalogues carry the real measured columns; a TAP/ADQL service over them is architecture-ready.

No TAP service is hosted. The catalogues hold the real columns (RA/Dec, magnitudes, distances); a TAP/ADQL endpoint is architecture-ready, not live.
