McGrath <address@hidden> regarding XML and netCDF. He's done an experiment translating netCDF to HDF5, described here: http://hdf.ncsa.uiuc.edu/HDF5/XML/nctoh5/writeup.htm He tells me that he was using an unofficial DTD for netCDF, but that Unidata may be working on an "official" DTD for netCDF. Is anyone working on this?John Caron has developed the appended DTD for netCDF. He also wrote "Comparison of 3 NetCDF DTDs" which refers to the McGrath paper and describes the differences among the existing DTDs. I can't find a reference to an online version of his comparison, so I'll CC: him on this reply, hoping he can provide it.
its pretty modest, but here it is: http://www.unidata.ucar.edu/staff/caron/xml/NetcdfCompare.htm also now there is a link to it from my home page.
