span-crossref-fastproc

Overview ¶

span-crossref-fastproc takes a raw crossref daily data slice (zstd compressed) and produces a solr-importable file by running the equivalent of: span-import -i crossref | span-tag -unfreeze filterconfig.zip | span-export -with-fullrecord.

The filterconfig can be supplied as a frozen zip file (-f) or fetched directly from FOLIO API (via OKAPI_URL and OKAPI_TOKEN env vars), with automatic caching.

Usage:

span-crossref-fastproc -o /output/dir feed-2-index-2026-03-02-2026-03-02.json.zst
span-crossref-fastproc -f filterconfig.zip feed-2-index-2026-03-02-2026-03-02.json.zst
