Do you read the entire stream into memory and then write it
back out, or do block I/O?And why modify/read ANY object

Yes, that is what you should be doing...

Okay, I am STUCK. I can play with XMP/RDF, that's
fine, and I've been doing it. But I am finding myself
unable to actually change the metadata of a given PDF.
I have culled together a fairly short example; can
anyone see any obvious problems?
import java.io.FileOutputStream;
import
One obvious problem is that this example was using
PdfStream, which always returns null from toPdf.
However, I had already been using PRStream before that
with the same results. I am going back to PRStream in
the debugging to which I have been forced to turn, due
to the terrible problem of time

PdfStream.toPdf() is implemented as always returning
null. I didn't know why that should be, so I changed
it. It was:

Dunno, I tried Jena without success, possibly I should
try a little longer with it, but it almost seems
easiest to go with generic XML parsing. Thanks,

The Adobe XMP Toolkit is the best, but that assumes Mac OS or
