Hi, I have put a proposal of a roadmap for the metadata features in Tika on the wiki: http://wiki.apache.org/tika/MetadataRoadmap
The proposal is based on a discussion around this topic I have had with Jukka. Please review and feel free to edit the wiki for the discussion. I will also update the wiki according to the discussion. BTW, how do I attach an image on that wiki? The documentation mentions the "attachment" link, which I am not able to find. Thanks Jörg
