Open Archive Initiatives (OAI)

As an organization committed to the wider dissemination of knowledge, BNJ supports the OAI Metadata Harvesting Protocol (OAI-PMH Version 2.0).

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is used to govern the collection of metadata descriptions and enables other archives to access the BNJ database. The Protocol has been developed by the Open Archives Initiative based on ensuring interoperability standards in order to ease and promote broader and more efficient dissemination of information within the scientific community.

BNJ has adopted the Protocol to increase accessibility, with resulting benefits for scholars, researchers, students, libraries, universities, and other academic institutions. Through this method of exposing metadata, BNJ enables citation indexes, scientific search engines, scholarly databases, and scientific literature collections to gather metadata from our repository and make our publications available to a broader academic audience.

As a Registered Data Provider, metadata for published articles are available via our interface at the base URL:
