Limits
  • per-ip-shaping transfer is limited to 3 MB/file and 10 MB total source
  • per-object-cap (binding) 3 MB/file source
  • per-object-cap (binding) 200 MB cap source
Per-object-cap 200 MB (soft, varies with traffic); FTP staging 5 GB / 31 days; the deposit must be a scholarly document with a document type, so raw data blobs are out of scope. arXiv transfer is limited to 3 MB/file and 10 MB total.
Identityinstitution (placeholder) inferred from the category 'academic'; the source record states no identity cost, so this is a class assumption, not evidence
EgressFree public PDF/fulltext download, no metering; metadata is harvested by OpenAIRE, BASE, Google Scholar.
Per-object cap200 MB maximum per file (200000000 bytes)
Retention| Very stable national infrastructure (CCSD/CNRS) with permanent URLs, but the per-file 200 MB cap and the bibliographic-record model make it useless for bulk blobs; the 5 GB FTP space decays in 31 days. (31 days)
Interfacerest, ftp rest
ToolingDeposit API + SWORD for programmatic submission (api.archives-ouvertes.fr/docs), FTP staging at ftp.ccsd.cnrs.fr with explicit TLS (FileZilla), OAI-PMH, and a TripleStore. This is a genuinely automatable write path.
Composes withUnlimited deposits x 200 MB/file — 2,500 files for 500 GB, but each deposit is a bibliographic notice, so the multiplier is records not blobs. 5 GB FTP staging expires in 31 days.
ReliabilityVery stable national infrastructure (CCSD/CNRS) with permanent URLs, but the per-file 200 MB cap and the bibliographic-record model make it useless for bulk blobs; the 5 GB FTP space decays in 31 days.
