The current version of imzML is 1.1.0. It has been announced on August 31st at the IMSC in Bremen. imzML has been extensively discussed with users and vendors at various occasions. If you have any comments, questions or suggestions please post them in the imzML forum.
The most important point is to extend the controlled vocabulary to meet the needs of different users, applications and data types. Two items which can NOT be changed are the separation in two files (necessary for efficient storage) and the mzML-based structure of the metadata file.
