OAI-PMH
We use the jOAI project as an OAI-PMH server that OpenAIRE can scrape.
We provide XML files in the oai_datacite
metadata format in order for jOAI to work.
We've developed a small Java program that scrapes the RSD API for releases of software, scrapes the DataCite OAI server for its metadata and saves the metadata as XML files.
