HelioAI speasy parameter index
The search index HelioAI queries to find a
heliophysics data product: ~82 000 parameters from the archives
speasy reaches — AMDA, CDAWeb, the Cluster Science
Archive, SSCWeb — each described as text and embedded with
sentence-transformers/all-MiniLM-L6-v2.
helioai index downloads it on a fresh install instead of building it; there is no need
to fetch it by hand.
How it is made
The Index workflow of the HelioAI repository builds it from scratch at every release tag
(helioai index --rebuild, no API key) and exports it with helioai index --export. The
tag of each release (v0.4.0, …) holds the index that release's code describes; main
holds the most recent one. A snapshot holding fewer than 95 % of the products expected is
refused rather than published: it means an archive did not answer during the build.
Files
manifest.json— format, HelioAI and speasy versions, embedding model, build date, and per collection the entry count, the vector dimension and a SHA-256 per file.products.jsonl.gz,catalogs.jsonl.gz— one JSON line per entry (id,document,metadata), in insertion order.products.npy,catalogs.npy— float32 embeddings, row i for line i.
Sources and licence
The descriptions are the archives' own metadata as speasy exposes it, and remain theirs; data obtained through them should be acknowledged as each archive asks — AMDA (CDPP), CDAWeb and SSCWeb (NASA SPDF), the Cluster Science Archive (ESA). The index itself — its assembly, the measurement type and region HelioAI adds to it, and the embeddings — is released under the MIT licence, as HelioAI is.
