Mapping for the ion mobility terms about mzml

[chambm]

Maybe I should move this to the CV repository?

I think it is okay here, we can address it here, but I don't really understand how you want to solve this. Can you maybe add a little more info with a proposed solution?

Also, there's no PSI-MS call this week due to travel, but I'm hoping we can resolve this next Friday. Might you be able to join the call next Friday to help clarify a proposed solution?

The proposed solutions are simple: for these terms, either replace "ion selection attribute" with "scan attribute" or add "scan attribute" to the list. Which one to use depends on whether we need to preserve semantic validity for any existing mzMLs that put the ion mobility attributes in the selectedIon element. I'm not aware of any that do.

The CCS issue is a bit more complex, probably worth discussing on a call. I'll try to join.

Joshua pointed out that ion mobility attribute is in fact a scan attribute, and the ion selection attribute is appropriate for selectedIon when referring to the precursor's ion mobility. So this is a non-issue. Except for the CCS thing. As discussed on the PSI call I'll make a PR for co-parenting the CCS as an ion mobility attribute.
