Every article receives a DOI — Crossref and Zenodo

Every article published in the journal receives a persistent digital object identifier (DOI), registered in two systems:

• Crossref — the journal's primary DOI registry, prefix 10.55439, which citations and links resolve through.
• Zenodo — the open repository supported by CERN. The full text is archived there and given its own DOI, so the article stays available independently of the journal site.

A citation therefore stays resolvable even if the site address changes. Article metadata is exposed over OAI-PMH and indexed by Google Scholar.
