This was the first version of the mzIdentML format, released August 2009.
mzIdentML was developed as an extension to the Functional Genomics Experiment (FuGE) object model. However, in a change agreed at the PSI Spring Meeting, 2008, the XML schema was developed directly rather than performing the design in UML and converting to XML. A cut-down version of the FuGE xsd has been developed to facilitate this. As a consequence, the UML class diagram in subversion is now out of date.
