KOSSDA OAI-PMH Repository Interface is one of 5 APIs that [Seoul National University](https://apis.io/providers/snu/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include OAI-PMH, Research Data, DSpace, Social Science, and Data Archive. The published artifact set on APIs.io includes an OpenAPI specification.

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.
