Several initiatives are underway to develop data-reporting standards modeled on the MIAME guidelines for DNA microarray data. A number of papers relevant to proteomics data standards are under consideration for publication in the journal Nature Biotechnology. In the coming weeks they will be made freely available for public comment at http://www.nature.com/nbt/consult/index.html. We encourage you to read the papers and submit your suggestions and criticisms, which will be carefully considered by the authors, reviewers and editors of Nature Biotechnology.
