Re: [Psidev-ms-dev] mzML 0.99.0 submitted to document process

Hi Lennart,

I'm not sure I understand, but my guess is that what's being said here is
that most CV additions are just leaves on the inheritance tree, along the
lines of our example of the introduction of "Super Ion Trap Turbo", and are
minimally disruptive.  Such additions would be minimally disruptive to a W3C
schema as well, as long as it doesn't bother with restriction elements for
things like instrument names, which it really shouldn't (it's not an error
to come up with a new instrument name value).  Thus the addition of
instrument type "Super Ion Trap Turbo" to the CV would not provoke a rev of
the the W3C schema, so that's nothing to worry about if we went that route.


Come to think of it, it sounds a bit like that mapping file is just another
dialect of schema?  Maybe we're nearly there already.

But I'm pretty sure I didn't understand... perhaps an example would help?

Thanks,

Brian

The fact that the mapping file most often does not need to be updated to 
operate correctly after CV changes, since it is based on the CV 
structure (term-to-term links) rather than the actual accession numbers. 
Indeed, for many CV param elements, the required (allowed) accession 
numbers for that alement are not even in the cv mapping.


Cheers,

lnnrt.
