Reagent Terms in PSI-MS

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I would be interesting to define the proper CVTerm in the PSI-MS for 
different reagent to be use for search 
    engines. This Param should be use in the metadata: 
  MTD   assay[1]-quantification_reagent 
    We can use the PRIDE Terms like http://www.ebi.ac.uk/ontology-lookup/browse.do?ontName=PRIDE&termId=PRIDE:0000433&termName=Reagents%20used%20in%20Labeled%20Methods
    but we should move some of them to PSI-MS.
2.
3.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

@germa can we add some of the PRIDE Terms for Quantitation to PSI-MS for example:

assay[1]-quantification_reagent
