HAL Open Archive Search API
HAL Open Archive Search API
CCSD's keyless search API (api.archives-ouvertes.fr) over deposit metadata in HAL, the French multidisciplinary open archive of articles, theses, preprints and other deposits, using Apache Solr query syntax and returning JSON or XML.
Required Attribution:
Not required for CC0 metadata. Full-text files follow their own per-deposit licence terms.
Coverage
Bibliographic metadata for HAL deposits, including each deposit's file licence. The CC0 licence covers metadata only; full-text files keep the licence chosen for each deposit, which can be a Creative Commons licence, the Etalab Licence ouverte or copyright. History start and update frequency: Not stated.
Verdict
Keyless Solr-syntax search API for HAL deposit metadata. Licensed CC0-1.0 (metadata): HAL's reuse-conditions page says (French; Signal Lab translation in brackets): "En revanche, la licence CC-0 s'appliquera bien automatiquement aux métadonnées de l'ensemble des dépôts." [However, the CC-0 licence will indeed apply, without further action, to the metadata of all deposits.] Full-text files carry their own per-deposit licences, which may be more restrictive than CC0. Rate limits: Not stated. Signal Lab links only.
