Hi Chris:Im guessing you actually want the netcdf-java libraries ( I have cross posted to netcdf-java@xxxxxxxxxxxxxxxx which is the correct email group for that). We unfortunately dont use Maven and dont have any expertise in it. We have had some contributed POM files by users. We would be willing to upload jar files automaticallly if theres a simple way to do that (add to our ant build?). Do we have to build with maven to do so? Of course, the complication comes from the dependencies.
From your Jira entry, it seems theres some question about files vs streams. netcdf is a random access file format. The java library does handle streams, but only by loading it into memory, as apparently youve discovered. If you are only interested in the metadata from netcdf-3 formatted files, all of the metadata is in the front of the file, and its usually quite small, so one could optimize that. For HDF5/netcdf4 the metadata is usually scattered around the file, so theres no easy way currently to optimize that. netcdf-java handles a lot of file formats, but all are assumed to be random access.

Hi Folks, I never heard back regarding this message. Any thoughts? Thanks!

Tika uses Maven2 as its build tool, and I was having trouble finding a copy of the NetCDF jars in the Maven Central repos. Would you guys be willing to upload/publish the NetCDF jars into Maven Central so that we could integrate them into Apache Tika? Right now, I've worked around this problem by using the following external NetCDF repo [3], but as Jukka Zitting informed me on the Tika mailing lists, per current Maven policies, it's bad practice to reference external repositories in POMs meant to be released to Maven Central [4]. It looks like you guys had some discussions about this before [5], but it's unclear if a consensus was reached. Please let me know, your help would be appreciated!
