The Journal of Clinical Advances in Dentistry (JCAD) supports Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) to ensure interoperability with international indexing services, repositories, and digital libraries. OAI-PMH compliance facilitates the automated harvesting of metadata, ensuring the journal’s content is discoverable and preserved globally.

What is OAI-PMH?

OAI-PMH is an international protocol developed by the Open Archives Initiative to enable standardized harvesting of metadata from scholarly repositories. It is widely used by libraries, indexing databases, and archiving services to collect bibliographic records in a structured, machine-readable format.

Supported Metadata Formats

JCAD supports multiple metadata formats to ensure interoperability with diverse harvesting systems:

• Dublin Core (oai_dc) – Basic bibliographic metadata
• METS/MODS – Complex descriptive metadata
• JATS XML – Journal Article Tag Suite, widely used in scholarly publishing
• CrossRef Metadata – Including DOI identifiers and references

How Indexers Use OAI-PMH

By exposing structured metadata through OAI-PMH, JCAD enables services like:

• Google Scholar and BASE to harvest article metadata
• DOAJ to verify open access compliance
• LOCKSS and PKP Preservation Network to archive content
• Institutional Repositories to import metadata for local visibility

Examples of OAI-PMH Requests

Users and harvesters can access metadata using standard OAI-PMH requests:

• Identify the repository: ?verb=Identify
• List metadata formats: ?verb=ListMetadataFormats
• List all records: ?verb=ListRecords&metadataPrefix=oai_dc
• Fetch a specific record: ?verb=GetRecord&identifier=oai:jcad:123&metadataPrefix=oai_dc

Compliance and Best Practices

The journal follows OpenAIRE and DOAJ metadata guidelines for maximum compatibility. Each record includes DOIs, author ORCID identifiers, abstracts, keywords, and funding information when available. This ensures discoverability across global repositories and compliance with funder mandates.

Benefits of OAI-PMH for Authors

• Enhanced visibility and discoverability of published work
• Improved indexing in global repositories and search engines
• Long-term preservation through multiple metadata archives
• Compliance with institutional and funder requirements

FAQs

Do authors need to register for OAI-PMH?

No, OAI-PMH is an automated protocol managed by the journal’s system.

How often is metadata updated?

Metadata is updated in real time upon article publication or revision.

Can institutions harvest metadata directly?

Yes, institutional repositories can integrate our OAI endpoint into their systems.
