This is a proposal for the UTI's (Uniform Type Identifier) to be used
by applications supporting NetCDF on Mac OS X for typing files.
More information on this topic is available on:<http://developer.apple.com/documentation/Carbon/Conceptual/ understanding_utis/understand_utis_intro/chapter_1_section_1.html>
It's practically a reversed dns "file-extension" for a fileformat. It is not visible to the enduser but used by apps to identify files it can open/edit.
For a general NetCDF file I think it would be something like this in an Info.plist:
<key>LSItemContentTypes</key> <array> <string>edu.ucar.unidata.netcdf</string> </array> <key>UTImportedTypeDeclarations</key> <array> <dict> <key>UTTypeIdentifier</key> <string>edu.ucar.unidata.netcdf</string> <key>UTTypeReferenceURL</key> <string>http://www.unidata.ucar.edu/software/netcdf/</string> <key>UTTypeDescription</key> <string>NetCDF File</string> <key>UTTypeIconFile</key> <string>netcdf_document</string> <key>UTTypeConformsTo</key> <array> <string>public.data</string> <string>public.content</string> </array> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>cdf</string> <string>nc</string> </array> <key>public.mime-type</key> <string>application/x-netcdf</string> </dict> </dict> </array>For NetCDF files containing data stored in a specific way, such as MS data in the ANDI specification, it would be:
<key>LSItemContentTypes</key> <array> <string>edu.ucar.unidata.netcdf. andi </string> </array> <key>UTImportedTypeDeclarations</key> <array> <dict> <key>UTTypeIdentifier</key> <string>edu.ucar.unidata.netcdf. andi </string> <key>UTTypeReferenceURL</key><string>http://pubs.acs.org/hotartcl/tcaw/98/may/stan.html</ string>
<key>UTTypeDescription</key> <string>NetCDF/ANDI File</string> <key>UTTypeIconFile</key> <string>netcdf_document</string> <key>UTTypeConformsTo</key> <array> <string>edu.ucar.unidata.netcdf</string> <string>public.data</string> <string>public.content</string> </array> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>cdf</string> <string>nc</string> <string>andi</string> <string>aia</string> </array> <key>public.mime-type</key> <string>application/x-netcdf-andi</string> </dict> </dict> </array>UTTypeIconFile entry is dependent on the name of the icon in the application bundle so not very relevant here. I am not exactly aware if there are any specific MIME types already is common use, if so, I'd be happy to hear.
Any objections against the UTTypeIdentifier's proposed?
