Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a set of specifications for making structured open repository metadata accessible to other service providers issuing requests. |
Why learn about OAI-PMH?
Taking advantage of repositories (data providers) and services (service providers) that offer metadata using OAI-PMH will allow your resources better visibility and access. For example, many discovery services (the “harvester”) use OAI-PMH metadata for indexing open access institutional repository articles.
The Basics
Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) specifies how metadata is structured and presented for ingestion by external services, usually on the Internet. OAI-PMH metadata is encoded in extensible markup language (XML) format. OAI-PMH records are harvested using HTTP requests.
OAI-PMH is a project of the Open Archives Initiative.
