University Of Tubingen Rate Limits

University of Tübingen publishes no rate-limit documentation page, but its FDAT research data repository advertises a concrete, machine-readable limit in response headers. A GET of https://fdat.uni-tuebingen.de/api/records/zvknn-g0x34 on 2026-09-01 returned X-RateLimit-Limit: 500, X-RateLimit-Remaining: 499, X-RateLimit-Reset: 1788292918 and Retry-After: 60 — a 500-request window with a 60-second reset, enforced per client by the InvenioRDM deployment. The OAI-PMH providers publish no headers; FDAT's robots.txt sets Crawl-delay: 10 and disallows /api and /search, which is the operator's stated harvesting posture even though the endpoints themselves are open.

No numeric limit is advertised in headers. FDAT's robots.txt declares Crawl-delay: 10, i.e. six requests per minute is the operator's stated polite-harvest rate; treat it as guidance, not an enforced ceiling.

Policies

Backoff Strategy
Exponential backoff with jitter; honor Retry-After (60s on FDAT); harvest during off-peak hours.
Crawl Delay
FDAT robots.txt sets Crawl-delay 10 and disallows /api and /search for crawlers.
