What is the Metadata Tools Project?

• An ESM (ECMAScript Module) for working with identifiers used by libraries and archives in TypeScript

Why create the Metadata Tools Project?

If you working in Python you can use idutils. I needed a similar capabilities in non-Python code spaces like my web browser or Deno. With Metadata Tools perform similar function server side (via Deno) and browser side, in other languages via compile to WASM or in the web browser via transpilation to JavaScript.

Metadata Tools seeks to be very portable across languages that support WASM, native binary executables and in web browsers.

What identifiers does it support?

• ArXiv ID
• DOI
• ISBN
• ISSN
• ISNI
• ORCID
• PMID
• PMCID
• ROR
• LCNAF
• VIAF
• SNAC

How do I use Metadata Tools in TypeScript and Deno?

import * as mt from 'https://caltechlibrary.github.io/metadatatools/mod.ts';

Example source

import {
  normalizeDOI, normalizeORCID, normalizeROR,
  validateDOI, validateORCID, validateROR,
  verifyDOI, verifyORCID, verifyROR,
} from "./mod.ts";

const orcid = "0000-0003-0900-6903",
  verifiedORCID = await verifyORCID(orcid),
  ror = "https://ror.org/00mpvse27",
  verifiedROR = await verifyROR(ror),
  doi = "https://doi.org/10.1128/jmbe.00128-21",
  verifiedDOI = await verifyDOI(doi);

console.log(
  `ORCID ${normalizeORCID(orcid)} -> is valid? ${
    validateORCID(orcid)
  } -> verfied? ${verifiedORCID}`,
);
console.log(
  `ORCID ${normalizeROR(ror)} -> is valid? ${
    validateROR(ror)
  } -> verfied? ${verifiedROR}`,
);
console.log(
  `ORCID ${normalizeDOI(doi)} -> is valid? ${
    validateDOI(doi)
  } -> verfied? ${verifiedDOI}`,
);

Example output

ORCID 0000-0003-0900-6903 -> is valid? true -> verfied? true
ORCID https://ror.org/00mpvse27 -> is valid? true -> verfied? true
ORCID 10.1128/jmbe.00128-21 -> is valid? true -> verfied? true

Roadmap?

Metadata Tools is still at the early experimental stage. Some ideas for future directions include targetting WASM in additional to a native binary for mdt cli. This would allow Metadata Tools to be used from languages that can import and run WASM modules (e.g. Rust, Python and Go).

Add additional identifier support as needed.
