OAI-PMH Metadata Harvesting
JBRES supports the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), enabling automated metadata retrieval by digital libraries and aggregators.
What Is OAI-PMH?
The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a low-barrier mechanism for repository interoperability. It allows metadata from JBRES articles to be harvested by academic search engines, digital libraries, and institutional repositories automatically and in a structured way.

Harvesters should use this URL as the base endpoint. All standard OAI-PMH verbs are supported.
Supported Verbs
JBRES supports all six OAI-PMH verbs:
- Identify — returns information about the repository
- ListMetadataFormats — lists available metadata formats (Dublin Core supported)
- ListSets — lists available sets (subject groups)
- ListIdentifiers — lists item identifiers with optional date-range filtering
- ListRecords — retrieves full metadata records
- GetRecord — retrieves an individual record by OAI identifier
Metadata Format
JBRES currently exposes metadata in Dublin Core (oai_dc) format. Each record includes: title, creator(s), subject, description (abstract), publisher, date, type, format, identifier (DOI), source, language, and rights (CC BY 4.0).
Sample Requests
Identify the repository:
https://oai.jelsciences.com/?verb=Identify
List all records (Dublin Core):
https://oai.jelsciences.com/?verb=ListRecords&metadataPrefix=oai_dc
List records since a date:
https://oai.jelsciences.com/?verb=ListRecords&metadataPrefix=oai_dc&from=2024-01-01
Usage Policy
Metadata is freely available for harvesting under the Creative Commons Attribution 4.0 (CC BY 4.0) license. Harvesters must credit JBRES as the source and must not use metadata for commercial spam or unsolicited contact with authors.
