OAI-PMH

The Annals of Civil and Environmental Engineering (ACEE) supports interoperability and long-term accessibility through implementation of the Open Archives Initiative Protocol for Metadata Harvesting (OAI‑PMH) version 2.0.

What Is OAI‑PMH?

OAI‑PMH is a standardized, low‑barrier protocol based on XML over HTTP, enabling repositories to expose structured metadata. Service providers can harvest this metadata efficiently, facilitating aggregation and indexing across systems :contentReference[oaicite:1]{index=1}.

Metadata Coverage & Formats

ACEE exposes metadata for all published articles using the Dublin Core (oai‑dc) schema. Metadata includes key fields such as title, author(s), abstract, DOI, publication date, and identifiers. Additional metadata formats may be supported as needed.

Technical Structure & Harvesting Workflow

ACEE’s OAI‑PMH endpoint supports the six core service verbs:

  • Identify – repository metadata
  • ListMetadataFormats – available schemas
  • ListSets – content grouping
  • ListIdentifiers – item identifiers
  • ListRecords – metadata harvesting
  • GetRecord – single record retrieval

Harvesting supports date-based deltas and set-based filtering for efficient incremental updates.

Benefits & Use-Cases

  • Automated indexing: Enables inclusion in discovery systems and institutional aggregators.
  • Metadata harvesting: Supports repository systems and union catalog construction.
  • Data interoperability: Machine-readable metadata ensures seamless integration across platforms.
  • Future-readiness: Supports evolving standards and metadata frameworks.

Repository & Service Integration

ACEE’s metadata is accessible to global service providers—including university repositories, digital libraries, and archival platforms—for inclusion in aggregators and search services.

Access & Support

Technical documentation for the OAI‑PMH endpoint—such as repository base URL, supported metadata prefixes, harvest schedule, and usage standards—is available to authorized partners upon request.

Compliance and Standards

ACEE’s OAI‑PMH implementation adheres to version 2.0 specifications and the network model defined by the Open Archives Initiative, ensuring metadata quality, structured transparency, and harvesting reliability.
