Tim Allison commented on TIKA-2018:
-----------------------------------
I'm not against implementing some basic heuristics based on font size to
extract the title as long as we keep the "extracted title" under a separate key
from the actual "dc:title" (and, y, I agree "when they are set" is a key
limitation).
PDF-Inspector's license (GPL 2 or later) is not compatible with Apache.
Can you submit a patch or recommend implementation details from, say, Beel et
al?

> A vast majority of pdf documents don't fill meta information.
> As a matter of fact, Tika won't be able to get information like the title.

> document explaining how to get the title from styles present in the document

> Also, I have tested another lib https://github.com/Docear/PDF-Inspector which

> which is not relevant with Hadoop and Nutch context, It would have been nice
> if it would have worked with stream.
> What do you think ?
