Annual Spring Meeting of the Proteomics Standards Initiative 23-25 April 2008, Toledo, Spain

The role of the Human Proteome Organisation Proteomics Standards Initiative (HUPO-PSI) is to produce and release community-accepted reporting requirements, interchange formats and controlled vocabularies for mass spectrometry proteomics and related technologies such as gel electrophoresis, column chromatography and molecular interactions. A number of significant advances were made at this workshop, with the new MS standard, mzML, being finalised prior to release on 1^st June 2008 and analysisXML, which will allow protein and peptide identifications and post-translational modifications to be captured, being prepared to enter the review process this summer. The accompanying controlled vocabularies are continuing to evolve and a number of standards papers are now being finalised prior to publication.
