RE: XMP Metadata extraction

["Withanage, Dulip" <wi...@asia-europe.uni-heidelberg.de>]

Hi Nick,

1. I tried calling the --medatadata option  and it gives me the   metadataname:value.
So this looks promising to me, if i could format the above output  as xml.
what is your advice to do it the best way?

2. I have seen the xmp class org.apache.tika.parser.image.xmp.xmp.XMPPackerScanner
Is there anyway to use this as default  parser for the jpeg and tiff. Can it be done by configuring in the tika-mimetypes.xml ?

Thanks,

Dulip

How are you calling Tika?

Also, I think that all the metadata you want is available in the Metadata
object, so you can likely just read it out of there. Try having a play
with the --metadata option to tika-app.jar (the demonstration command line
tika program)

You'll probably want to write some java code at this point, rather than 
just calling the tika app on the command line. Grab the Metadata object 
back, then loop over the entries and output them as XML in whatever format 
you want them to be in.

Nope, tika-mimetypes.xml is used for detection, and the parser stuff is 
different.

XMPPackerScanner isn't a parser though, but instead is called by the 
existing parsers when they detect XMP metadata within a file. The existing 
JPEG and TIFF parsers already do this for you
