About the HUPO Proteomics Standards Initiative (PSI)

The Human Proteome Organization Proteomics Standards Initiative (HUPO PSI) is a global collaborative effort aimed at creating and maintaining community-driven standards, data formats, and controlled vocabularies for proteomics and mass spectrometry-based research. Through its working groups and annual workshops, HUPO PSI encourages collaboration and ensures thorough public review of proposals before their adoption as standards. By advocating for open data sharing, the initiative accelerates advancements in proteomics and related scientific fields.

HUPO PSI establishes community standards for data representation in proteomics to enable seamless data comparison, exchange, and verification. The initiative was founded during the HUPO meeting held in Washington on April 28–29, 2002 (see Science 296, 827). It is important to note that HUPO PSI does not address quality issues in individual datasets.
