Hi Chris:
We havent really got our act together on the external svn yet, so its a
bit messy.
generally you check everything from:
http://svn.unidata.ucar.edu/repos/thredds/trunk/
<http://svn.unidata.ucar.edu/repos/thredds/trunk/cdm/> to {local}/thredds
http://svn.unidata.ucar.edu/repos/common/java/trunk/ to
{local}/unidataCommon
the java-netcdf build is in {local}/thredds/cdm/build.xml
its possible to get the grib source and opendap source, but i think the
ant build will use the jar files in
{local}/thredds/lib/**
which i think is the right thing to do for the moment. we are going to
move the grib source under thredds, so next round we can incorporate
that. im not yet sure of opendap - for now assume its independent.
we might see what contortions your patch brings and try to clean up our
act some.
thanks

(copying tika-dev@xxxxxxxxxxxxxxxxx so that we can get some dev help
in Tika-land)
Hi John,
Thanks for the information --- we have a number of experienced
developers over in Tika-ville that likely can help provide a patch to
your ant build scripts to upload via Ant (and likely Ivy) to the Maven
Central repos. Jukka Zitting is one of the masters of Maven Central
and of Maven in general --- Jukka, do you know how to use Ant, with
e.g., Ivy, to help out the NetCDF-java'ers?
Thanks for the info too on the RandomAccessFile notion in netCDF. I
found it out while trying to process it in Tika, so ended up working
around it via the Tika interface and loading the stream into memory
first. Jukka is working on TIKA-153 [1] that builds a TikaInputStream
to handle these types of situations and provide a stream based
interface around situations like this :)
Thanks and we will be in touch: can you point us to your SVN and to
your ant build script so we know how to contribute a patch for you guys?
Thanks!
Cheers,
Chris

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.

Re: NetCDF jars=>Maven Central Repos? Hi Folks,
I never heard back regarding this message. Any thoughts?

Hi there NetCDF'ers,
We've been working [1] on integrating NetCDF support into
Apache Tika [2].
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!
Cheers,
Chris
