OAI PMH

1. Introduction Our platform supports the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH v2.0) to facilitate the discoverability and interoperability of institutional research data

2. Metadata Policy & Licensing

    • Access: All metadata exposed via our OAI-PMH interface is Open Access and freely available to any harvester.
    • Licensing: The metadata is dedicated to the public domain under the Creative Commons CC0 (Public Domain Dedication) license. Harvesters may copy, modify, and distribute the metadata without restriction.
    • Metadata Formats: The repository supports the mandatory oai_dc (Dublin Core) schema. For richer data structures, the oai_datacite format is also available.

3. Data Re-use & Attribution Guidelines

    • Service providers harvesting metadata from this repository must provide a direct hyperlink back to the original record page within any of our open access platform.
    • Harvested metadata must not be misrepresented, altered to distort its original scientific meaning, or sold commercially as a standalone dataset.

4. Technical Implementation & Throttling Policy

    • Rate Limiting: To ensure service availability, a maximum limit of 3 requests per second per IP address is enforced.
    • Pagination: Records are paginated using the resumptionToken mechanism, serving a maximum of 100 records per request page. Harvesters must respect and process the resumptionToken.
    • Bulk Harvesting Windows: For full-repository harvesting, service providers are highly encouraged to schedule tasks during off-peak hours (e.g., between 11:00 PM and 6:00 AM GMT+8).
