Metadata Interoperability
Last updated: 06/19/2026
Pensar – Journal of Legal Sciences adopts the OAI-PMH 2.0 protocol (Open Archives Initiative Protocol for Metadata Harvesting) as its open interoperability standard, allowing its metadata to be automatically harvested by indexers, aggregators, institutional repositories, and scientific discovery services worldwide.
OAI-PMH is the international reference protocol for interoperability between scientific journals and information services. It is used by databases such as DOAJ, BASE, Google Scholar, REDIB, Latindex, and Miguilim (IBICT), among others.
1. OAI-PMH endpoint address
The access address for Pensar's OAI-PMH protocol is:
https://ojs.unifor.br/rpen/oai
2. Available protocol verbs
The six verbs specified by OAI-PMH 2.0 are operational and can be queried directly:
- Repository identification (Identify)
- Available metadata formats (ListMetadataFormats)
- Record sets (ListSets)
- Identifier listing in Dublin Core (ListIdentifiers)
- Record listing in Dublin Core (ListRecords)
- Individual record retrieval (GetRecord), based on a specific OAI identifier.
3. Exposed metadata formats
Pensar exposes its metadata in the following standardised formats, retrievable through the ListRecords verb:
- Dublin Core (
oai_dc) — the OAI-PMH mandatory minimum format; - JATS (
jats) — structured format for scientific articles, adopted by SciELO and PubMed Central; - RFC 1807 — classic academic metadata standard.
4. Integration with discovery systems
Interoperability via OAI-PMH is what enables Pensar's articles to appear automatically and in updated form in international search and discovery databases, institutional repositories, university library systems, and open-access portals.
