Meyer

2 mzIdentML 1.1 sketch of changes Minor Changes: -elements: upper case, attributes: lower case -dateTime instead of string Minor Changes: -elements: upper case, attributes: lower case -dateTime instead of string Medium Changes: - merged with -residues:. allowed for terminal modifications Medium Changes: - merged with -residues:. allowed for terminal modifications during implementation of 1.0: ideas / need for changes: Only one.xsd file (FUGElight.xsd integrated)

3 Major Change: elements moved from to - is the actual PSM -Inferring proteins from peptides: actually PPSMs (protein-peptide-spectrum matches) - is the PP part of a PPSM Major Change: elements moved from to - is the actual PSM -Inferring proteins from peptides: actually PPSMs (protein-peptide-spectrum matches) - is the PP part of a PPSM mzIdentML 1.1 sketch of changes Reason for moving it: space savings, Enzyme can be referenced with new, (better human readability ?)
