Description

Tika only pull file level metadata for *.fits (flexible image transport system) files, using:

java -jar tika-app-1.18.jar --gui

Content-Length: 699840

resourceName: WFPC2u5780205r_c0fx.fits

Rather than text from the header (extracted with astropy.py):

SIMPLE  =                    T / file does conform to FITS standard             BITPIX  =                  -32 / number of bits per data pixel                  NAXIS   =                    3 / number of data axes                            NAXIS1  =                  200 / length of data axis 1                          NAXIS2  =                  200 / length of data axis 2                          NAXIS3  =                    4 / length of data axis 3                          EXTEND  =                    T / FITS dataset may contain extensions            COMMENT   FITS (Flexible Image Transport System) format is defined in 'AstronomyCOMMENT   and Astrophysics', volume 376, page 359; bibcode: 2001A&A...376..359H BSCALE  =                1.0E0 / REAL = TAPE*BSCALE + BZERO                     BZERO   =                0.0E0 /                                                OPSIZE  =                 2112 / PSIZE of original image                        ORIGIN  = 'STScI-STSDAS'       / Fitsio version 21-Feb-1996                     FITSDATE= '2004-01-09'         / Date FITS file was created                     FILENAME= 'u5780205r_cvt.c0h'  / Original filename                              ALLG-MAX=           3.777701E3 / Data max in all groups                         ALLG-MIN=          -7.319537E1 / Data min in all groups                         ODATTYPE= 'FLOATING'           / Original datatype: Single precision real       SDASMGNU=                    4 / Number of groups in original image    

 

This was capability was mentioned in Tika-874. I'm looking at netCDF files/headers as model for this behaviour. 

Thank you!
