Pomegranate
is a python application that webifies science data files.
Supported formats include netcdf, hdf4, hdf5, grib and fits.
It can be installed on web servers as either WSGI or CGI applications
to provide webification (w10n) services. To learn more about w10n of
science data files, please visit

It can also be used as a standalone library or command line application. This greatly simplifies the retrieval of meta and data information from files in supported formats.

Once Pomegranate is properly installed, some datasets in HDF files can be accessed using web browser. We'll use the NASA JPL's demo server for illustration. Please open the following URL in your web browser:
You'll get a list of HDF files served by the Pomegranate as shown in Figure 2 below.
Click the folder icon
under Webifiable column. You'll get a tree view like Figure 3 below:
Notice that URL now has '/?' after the HDF file name in your web browser.
Click the down arrow icon 
in any of dataset of your interest.
For example, if you click the down arrow next to the l3m_data,
you will see several new links pops up next to the arrow in two square brackets.
You can get JSON output of either attributes by clicking [meta: json] or data by clicking [data: ..., json] link.
The following Figure is the data output in JSON.
You'll get a small subsetted data in JSON format like Figure 6 below.
