Subject [jira] [Updated] (TIKA-1577) NetCDF Data Extraction
Date Tue, 17 Mar 2015 21:42:39 GMT

     [ https://issues.apache.org/jira/browse/TIKA-1577?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ann Burgess updated TIKA-1577:
------------------------------
    Description: 
A netCDF classic or 64-bit offset dataset is stored as a single file comprising two parts:
 - a header, containing all the information about dimensions, attributes, and variables except
for the variable data;
 - a data part, comprising fixed-size data, containing the data for variables that don't have
an unlimited dimension; and variable-size data, containing the data for variables that have
an unlimited dimension.

The NetCDFparser currently extracts the "header part".  
 -- text extracts file Dimensions and Variables
 -- metadata extracts Global Attributes

We want the option to extract the "data part" of NetCDF files.  
Lets use the NetCDF test file for our dev testing:  tika/tika-parsers/src/test/resources/test-documents/sresa1b_ncar_ccsm3_0_run1_200001.nc


 



  was:
We want the option to extract data associated with each NetCDF variable.  

For our development testing, lets use the NetCDF:  tika/tika-parsers/src/test/resources/test-documents/sresa1b_ncar_ccsm3_0_run1_200001.nc
