The next teleconference is scheduled for Feb 7 at 1600 GMT - please 
forward any agenda items for discussion.

The mzData specification is being completed so that review can occur at 
the April PSI meeting.  We are collecting "Use Cases", "Goals" and 
"Non-Goals" for the document so that common uses of the format can be 
explained.  Our idea of 'use case' is more like a scenario than a formal 
document.  Goals should state what the specification should achieve and 
non-goals should describe what is considered out of scope for the 
specification

Some examples that have been collected so far:

_Use cases for mzData: _
Store spectral data collected from an HPLC-MS experiment

Store tandem mass spectrum

Store processed peak list

Store Time-domain data supporting TOF peak list

Store FID data from FTICR to support peak list

Store continuous, high resolution spectra

Store selected ion monitoring experimental data

Compare spectra from the same sample analysed by two instruments from 
different manufacturers using a third party tool.

_Goals:_
Provide a vendor-independent representation of mass spectral data 
collected for use in proteomics analysis

Allow new experiments and new instruments to be represented via an 
expansion of a controlled vocabulary rather than a format change

Provide a controlled vocabulary derived from the standard IUPAC 
terminology for analytical chemistry and other standards groups

_Non-Goals:_
Representation of sample preparation methods and steps

Representation of biological sample origins

The format is not intended to be suitable as an internal file format for 
a mass spectrometry application that works with peak lists and/or raw 
mass spec data.
