oai-pmh's Introduction

OAI PMH

A nodejs module for the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH 2.0). Use this module if you want to harvest metadata from OAI-PMH providers, e.g., arxiv.

Note: This is a fork of oai-pmh.

Installation

npm install oai-pmh2

Note: Node >= 10 is required for this module (because it makes use of async generators).

Library

Example

You can run the following script with node -r esm:

import { OaiPmh } from 'oai-pmh2'

async function main () {
  const oaiPmh = new OaiPmh('http://export.arxiv.org/oai2')
  const identifierIterator = oaiPmh.listIdentifiers({
    metadataPrefix: 'oai_dc',
    from: '2015-01-01',
    until: '2015-01-04'
  })
  for await (const identifier of identifierIterator) {
    console.log(identifier)
  }
}

main().catch(console.error)

See OaiPmh in oai-pmh.js for all available commands.
