Giuseppe Totaro commented on TIKA-1302:
---------------------------------------

Thank you Chris.

I'm working with Tika against large set of data. Govdocs1 represents a good 
choice in order to test Tika performance with a large amount of heterogeneous 
documents. By using Tika 1.4, I noticed that about 10% of govdocs1 files are 
not correctly parsed.
Unfortunately, each file of govdocs1 corpus has the same metadata properties 
(http://digitalcorpora.org/corpora/files), so this corpus does not provide the 
possibility to realistically test metadata extraction.
After our paper will be published in proceedings, I will happy to describe 
results more in details and share them with the community.
Now, we're working also with other corpora constructed by ourself starting from 
realistic (unclassified) disk images.

I hope to meet your interests.

> Many thanks to [~lewismc] for TIKA-1301!  Once we get nightly builds up and 
> running again, it might be fun to run Tika regularly against a large set of 
> docs and report metrics.
> One excellent candidate corpus is govdocs1: 
> http://digitalcorpora.org/corpora/files.
> Any other candidate corpora?  
> [~willp-bl], have anything handy you'd like to contribute?
