New Working Group: Making Proteomics AI-Ready

The HUPO-PSI AI-readiness Working Group has launched, bringing together researchers to make public proteomics data more usable for AI through better metadata, formats, and reprocessing workflows. Chaired by Tine Claeys, with co-chairs Samuel Wein and Ralf Gabriels, the group welcomes anyone interested in shaping practical, community-driven solutions. Get involved and follow our progress!

Documents in progress and new documents

  • The mzQC format, a data standard for reporting and exchanging quality-related information in biological mass spectrometry, has been been released on February 21st, 2024
  • The mzIdentML 1.3.0 specification and its crosslinking extension have been released on July 4th, 2024.
  • The mzPAF (Peak Annotation Format – Peptides) specification has been released on September 22nd, 2025 
  • The mzSpecLib specification, a formal standard and file format to store and distribute spectral libraries, has been released on September 22nd, 2025
  • The FeatureTab, an exchange format for molecular interactions features, has been released on January 8th, 2026.
  • The Proforma 2.1 specification (Proteoform and Peptidoform Notation) is under revision after the external and public review phase that ended on December 10th, 2025.
  • An edited version of  the mzPAF (Peak Annotation Format – Peptides) with minor edits is now in a 14-day public review phase. Please participate and send your comments to the PSI editor (sylvie.ricard-blum[at]univ-lyon1.fr) before April 10th, 2026!
  • The MIDAP (Minimum Information Describing a Proteoform) document v.1.0.0 is now in a 30-day public review phase. Please participate and send your comments to the PSI editor (sylvie.ricard-blum[at]univ-lyon1.fr) before April 19th, 2026!
