•Develops data format standards for proteomics.•Both data representation and annotation standards.•Involves data producers, database providers, software producers, publishers, … as many interested parties as possible.
•Started in 2002, so some experience already…•One annual meeting in March-April, regular phone calls.

PSI Deliverables
•Formats: Usually an XML schema (but also tab-delimited files)
•Controlled vocabularies: Usually an OBO-style hierarchical controlled vocabulary precisely defining the metadata that are encoded in the formats.
•Minimum information (MIAPE) specifications: Format-independent specification of minimum information guidelines.
•Databases and Tools: Foster software implementations to make the standards truly useful.
•Community interaction to ensure deposition of data in public repositories.

Mass Spectrometry (MS)-based proteomics• Many different workflows -> Many different data types ->
Need for several data standards.
• Discovery mode:• Bottom-up proteomics
• Data dependent acquisition (DDA)• Data independent acquisition (DIA)
• Top down proteomics
• Targeted mode:• SRM (Selected Reaction Monitoring)

PSI document process
•Every data standard has to undergo a thorough review process…
• In fact, in practice, two review processes happen in parallel: the PSI and usually a manuscript review as well.

PSI MS Controlled Vocabulary
Mayer et al., Database, 2013~2,600 terms by February 2017

Objectives of the PSI in the next 5 years• Improve adoption/support, especially in vendors
software
• Extend current proteomics data standards to MS metabolomics
• Facilitate reproducible analysis pipelines.
• Finalize compatible formats with genomics data e.g. proBed & proBAM (applicable for proteogenomics studies)
• Start working with the structural biology community (since MS proteomics is being increasingly used in that context)
