KOSSDA OAI-PMH Repository Interface

OAI-PMH 2.0 metadata harvesting for KOSSDA (한국사회과학자료원), the Korea Social Science Data Archive at Seoul National University — SNU's social-science research data archive, listed in re3data as r3d100014654 with no API recorded there. Verified live and anonymous on 2026-08-19: adminEmail kossda@snu.ac.kr, earliestDatestamp 2017-04-09T11:10:50Z, same twelve metadata formats, handles under prefix 20.500.12236. DSpace 5.6 on 147.46.181.153, SNU's own address block. Two defects are recorded rather than smoothed over: the endpoint advertises its own baseURL as plain http:// while serving over HTTPS, and Identify needed a read timeout above 45 seconds to complete, which will fail most default harvester settings.

Where this information came from

This is an independent, third-party profile of KOSSDA OAI-PMH Repository Interface, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
