Re: Bringing spectroscopy into the COMCIFS fold

Hi, Peter,
thanks for your comments!

Well, at the moment we need to set up smooth data exchange for our SOLSAproject, so there is a need for common expandable spectroscopy standard;also, other people are looking for similar things, as I have learnedrecently.
The key point is that it needs to be simple -- we can not affordspending much time to implement a complicated format/standard.

Thanks, I'll have a look. Either we consider these standards, or takeparts from them to be compatible.

Well, vendor lock-in is something I am ready to fight against, and acommon open standard is worth having, if only for that reason.

We have several spectroscopy groups collaborating in our SOLSA project,and they expressed genuine interest in having a standard for datasharing. If we can come up with something simple enough, the investmentis worth doing -- and then we'll see.
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 thatstandard. If we can get these then the effort is worth it.
The worst thing that can happen is that people will start dumpingspectra in CSV files from Excel, without any standard or ontologywhatsoever. We would then risk loosing a lot of valuable measurementsjust because they are not properly documented.
