Well, at the moment we need to set up smooth data exchange for our SOLSA
project, so there is a need for common expandable spectroscopy standard;
also, other people are looking for similar things, as I have learned
recently.

Could be a good idea to post on the blueobelisk.org mailing list for ideas.
 

The key point is that it needs to be simple -- we can not afford
spending much time to implement a complicated format/standard.

dard is worth having, if only for that reason.

... Spectroscopy can be complicated (GC-MS-MS etc. So suggest we start with 1-D spectra HNMR CNMR UV-VIS

IUCr?

Worth asking. Let's suggest spectroscopy coupled to, or co-published with, crystal structures. That could avoid  inter-Union sensitivities.

We have several spectroscopy groups collaborating in our SOLSA project,
and they expressed genuine interest in having a standard for data
sharing. If we can come up with something simple enough, the investment
is worth doing -- and then we'll see.

My suggestion is to create and deploy a working toolset. That exists. People like Egon Willighagen and Chris Steinbeck will help. Show what can be done. 

I would say a standard is only as good as the software that supports it,
and only of there is considerable amount of available data in that
standard. If we can get these then the effort is worth it.

The worst thing that can happen is that people will start dumping
spectra in CSV files from Excel, without any standard or ontology
whatsoever. We would then risk loosing a lot of valuable measurements
just because they are not properly documented.

The worst thing - and it happens several million times a year - is to dump it as PDF, often bitmaps.
ARGHHH!
