Tim Allison commented on TIKA-2018:
-----------------------------------
bq. A vast majority of pdf documents don't fill meta information.
To confirm, you do _not_ mean that Tika is failing to pull metadata out of the
metadata component or the XMP within PDFs.
If you're trying to extract "metadata" from the content via nlp or other
heuristics, have you experimented with the [Grobid Journal
Parser|https://wiki.apache.org/tika/GrobidJournalParser]?

> 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
> with simple rules based heuristic. We can probably ask the source code on

> Also, I have tested another lib https://github.com/Docear/PDF-Inspector which
> does a great job. However, it seems to work exclusively using File object
> 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 ?
