This summer one of students in Google Summer of Code program, Peng Zhang, is writing a library for reading x-y data - all formats produced by diffractometers, spectrometers, MCAs, etc. I'm mentoring this project.
At this moment, we have a few powder diffraction formats (Bruker .raw v1-3, text formats: Bruker uxd, Philips udf, Rigaku dat, Sietronics cpi) and two spectroscopy formats: (ISO VAMAS and WinSpec SPE). If you have documentation of any other formats, you can send it to us ([EMAIL PROTECTED], [EMAIL PROTECTED]). We will be glad to add it to the library. Just send us one or more sample files and explanation of the format (e.g. scan of paper documentation). We are aware of two open-source programs, CMPR and ObjCryst, that can be helpful. We also know about conversion programs listed at CCP14 that, although closed-source, can be used for testing. Any other hints are welcome. The library (+ a simple conversion program) will be open-source (LGPL) and portable. I guess after a year or two it will be included in some Linux distributions, because it will be used by at least one package (fityk), that is already there (in Debian, Ubuntu, Fedora, Mandriva and a few other distros, and in FreeBSD).
