Subject Re: Tika API

Hi Ned,

 Glad to see you're poking around with the Tika software and its use in
Nutch. To start, you probably want to go to the website for Tika:

 On that website, you should see the links to the SVN repository. The
version of Tika that was used was a version that I built the same day I
committed the fix for NUTCH-562:

 Which appears to be a version of Tika built on October 8th. The API for the
mime framework has changed a bit since then (to its betterment), however, I
neglected to upgrade the Nutch API because of the strong objection I
received from Andrzej and input from Dennis Kubes regarding the use of the
Tika API in Nutch. I stand by my email I sent in reply to the objections:

 However, out of respect for the other committers, neglected to make any
updates to the Nutch use of the Tika API since I never heard back from
anyone after my response.

 That said, could you be a bit more specific Ned as to the exact problem
you're having, e.g., "I tried visiting this site (URL here), the content
type was (content/type here), and then it got into, and on line
XXX it seems that the MimeType is getting set to null when it tries to...".
With that info, I could probably help you quite a bit more. Also, depending
upon how the rest of the Nutch committers want to handle the use of Tika
(revert and remain stagnant, or use Tika and leverage the updates we're
making to the Mime framework there), then we could come up with a strategy
to help you out with the issue you're having.
