Through-the-web data browser for CDX datasets

Project Description

This is a through-the-web data browser for CDX, the Climate Data Exchange, an effort of the Jet Propulsion Laboratory (JPL). It serves as a “data portal” for climate data.

Although intended for the CDX web site, it can run on any Plone site.


If you’re stuck maintaining this package, note that it depends on the CDX client package. That’s all well and dandy, except that the client itself depends on PyHDF, which may look like a nice standard Python enhanced egg, but believe me, it’s not. OK, it probably is, but it depends on NumPY and HDF4, both of which are problematic.

Here’s what I ended up having to do:

  1. Pick a prefix, call it $PREFIX.
  2. virtualenv-2.6 –distribute –no-site-packages –prompt=cdxcrap $PREFIX
  3. cd $PREFIX
  4. bin/pip install numpy
  5. mkdir src
  6. cd src
  7. curl -L ‘’ | tar xjf -
  8. cd hdf-4.2.6
  9. ./configure –prefix=$PREFIX –without-szlib –disable-fortran
  10. make
  11. make install
  12. cd ..
  13. curl -L ‘’ | tar xzf -
  14. cd pyhdf-0.8.3
  15. env NOSZIP=1 INCLUDE_DIRS=$PREFIX/include LIBRARY_DIRS=$PREFIX/lib $PREFIX/bin/python2.6 install

You can then use $PREFIX/bin/python2.6 with this egg:

  1. $PREFIX/bin/python2.6 -d
  2. bin/buildout
  3. bin/test

Tests pass, so it must work!

cdxsite.databrowser Installation

Use zc.buildout and the plone.recipe.zope2instance:

  • Add cdxsite.databrowser to the list of eggs to install, e.g.:

    eggs =
  • Tell the plone.recipe.zope2instance recipe to install a ZCML slug:

    recipe = plone.recipe.zope2instance
    zcml =
  • Re-run buildout, e.g. with:

    $ ./bin/buildout

You can skip the ZCML slug if you are going to explicitly include the package from another package’s configure.zcml file.
