Hi Janko, > There was a shallow rumour here, that netcdf will not longer be > supported by unidata. Is this true, are there any dates? It's not true, we continue to maintain and support netCDF, and we have recently submitted a proposal to get resources for the development of netCDF-4. But I'm glad for the opportunity to update our netCDF plans in response to this rumor. We announced a beta test version of netCDF 3.5 in September 1999, and the RELEASE_NOTES detailing the bug fixes and enhancements included with netCDF 3.5 are available from http://www.unidata.ucar.edu/packages/netcdf/release-notes-3.5beta2.html Before creating the final release candidate for netCDF 3.5, I'm hoping to include one more major addition, an experimental Fortran 90 interface contributed by Robert Pincus of the University of Wisconsin. This is available now as a separate package from http://www.unidata.ucar.edu/packages/netcdf/f90/ This interface represents quite a simplification for Fortran users of netCDF, using Fortran 90's overloading and optional argument features to replace 110 functions in the Fortran 77 interface with only 31 functions in the Fortran 90 interface! The web page cited above also has links to a new NetCDF User's Guide for Fortran 90. We also have ambitious plans for netCDF-4 and have submitted a proposal to NSF to seek additional resources for this development: http://www.unidata.ucar.edu/packages/netcdf/itr/ > If that's not true I apologize for making noise, No problem, I'm glad you asked about support, because there may be a change in support policies in the next year. In the past we have always tried to answer netCDF-related email sent to "support@xxxxxxxxxxxxxxxx", whether from the core Unidata community of researchers and educators in the atmospheric sciences, from netCDF users in other disciplines, or from users in the commercial sector. More than 3400 replies to netCDF support questions are indexed by the glimpse search engine and accessible from the bottom of the netCDF home page. Although we value the bug reports and suggestions that netCDF users have sent us, we don't want to sacrifice further development to a growing netCDF support load. So for netCDF, we may try to establish a two tier support system, where questions from the core Unidata community get quick responses, but other netCDF questions are forwarded to a new mailing list, "netcdfsupport@xxxxxxxxxxxxxxxx", to see if other volunteer subscribers on that list can provide an answer first. > Than another question. Is someone working at a XML mapping for > netcdf, or does someone know of a more general XML mapping for > scientific data , besides XSIL, which could be used with netcdf data? One way to get an answer to this question is to follow these links to the indexed support email search page NetCDF home page: http://www.unidata.ucar.edu/packages/netcdf/ netCDF support email archive: http://www.unidata.ucar.edu/glimpsedocs/ghnetcdf.html then enter "xml" as a keyword, to get a page of links, including http://www.unidata.ucar.edu/glimpse/netcdf/3674 to find out there is software available for producing XML instead of CDL from a netCDF file, using an ncxdump utility developed by Bear Giles that is analogous to ncdump. A proposed DTD for this netCDF XML representation is available in the package referred to there, or separately from http://www.unidata.ucar.edu/packages/netcdf/dtd/ Thanks for pointing out XSIL <http://www.cacr.caltech.edu/XSIL/>. It looks quite promising, and may represent the future for scientific data access. --Russ _____________________________________________________________________ Russ Rew UCAR Unidata Program russ@xxxxxxxxxxxxxxxx http://www.unidata.ucar.edu
