Subject [jira] [Commented] (OODT-652) New TikaCmdLineMetExtractor
Date Thu, 29 Aug 2013 22:09:51 GMT

    [ https://issues.apache.org/jira/browse/OODT-652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13754116#comment-13754116

Rishi Verma commented on OODT-652:

Hmm.. interesting idea!

I've thought about integrating this somehow with StdProductCrawler, such that the user can
quickly ingest a product with some very useful metadata without having to write or configure
any extractors. Plugging this into a crawler action could definitely be a way to do that.
Thanks for the idea! 

>  i not sure why a new metadata extractor is need for this though...

The Tika extractor was necessary for me via the command-line (outside of the crawler framework).
This is why it exists as a separate extractor. No reason to not integrate it further into
the crawling framework though (as you suggested!).

> Often times, we want to ingest a product and have some basic metadata automatically extracted
from it without much effort. The Apache Tika project has great features supporting the detection
of and extraction of metadata associated with a product to this effect. The purpose of this
issue is to integrate these metadata extraction capabilities of Tika, so that OODT can easily
leverage and make use of them. 
> At a minimum, this issue seeks to:
> * Incorporate and use Tika's 'parse' method to extract metadata automatically
> * Include the text content (if any) of a document inside a new metadata element dubbed
'content'. This will be useful for lucene and solr based free-text searches
