Chris - could you elaborate on using Tika Jax-RS and DIH?  How 
production ready is it?  Could you summarize the steps necessary to get 
it to work?  Any examples yet?

I'd be happy to work with you to get something out to the group.


Thanks - Tod

Sure. I know that Maxim Valyanskiy has done a bunch of work with the Tika Jax-RS layer. It's a simple exposing of Tika met extraction and unpackaging capabilities via the JSR 311 spec. So you get REST services like:

/meta 
HTTP PUTs a document to the /meta service and you get back "text/csv" of the metadata.

/tika

HTTP PUTs a document to the /tika service and you get back the extracted text.
HTTP GET prints a greeting stating the server is up.

/unpacker

HTTP PUTs an embedded document type to the /unpacker service and you get back a zip of the extracted text for each resource filename in the original PUT embedded document type.

Basically you just build the tika-server WAR file, drop it onto a Servlet App Server (Tomcat, Jetty, etc.) and then you've got a Tika JAX-RS server.

Awesome! I've created a Tika Wiki page here:

http://wiki.apache.org/tika/TikaJAXRS

Since this is really also Tika related, please feel free to join user@tika.apache.org or dev@tika.apache.org by sending emails to:

user-subscribe@tika.apache.org
dev-subscribe@tik.apache.org

Then you can move the Tika portions of the conversation there. For the Solr/DIH side, this is the right list.

Cheers,
Chris
