What is this?

It’s a library for Node.js and Deno to easily communicate through “The Open Archives Initiative Protocol for Metadata Harvesting” with certain OAI-PMH hosts. It is targeting version 2 of OAI-PMH.

Example:

// Node.js
import { OaiPmh, OaiPmhParser } from "oai_pmh_v2";
// Deno
import { OaiPmh, OaiPmhParser } from "https://deno.land/x/oai_pmh_v2/src/mod.ts";

(async () => {
  const oaiPmh = new OaiPmh({
    baseUrl: "https://www.hindawi.com/oai-pmh/oai.aspx",
    xmlParser: new OaiPmhParser(),
  });
  for await (
    const gen of oaiPmh.listSets({ signal: AbortSignal.timeout(60000) })
  ) {
    for (const value of gen) {
      console.log(value);
    }
  }
})().catch(console.error);
