Subject [jira] Updated: (TIKA-7) Lius Lite remove all lucene dependencies from Lius and use Nutch office parsers
Date Wed, 13 Jun 2007 08:17:26 GMT

     [ https://issues.apache.org/jira/browse/TIKA-7?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jukka Zitting updated TIKA-7:
-----------------------------

    Attachment: liuslite.patch

I took the sources (and associated config and test files) from liuslite.zip and placed them
inside the svn trunk following the standard Maven 2 layout. See the attached liuslite.patch
file for the result.

Summary of changes:

* I replaced all tabs with four spaces each.
* I placed liusLite/src/junit to src/test/java/org/apache/tika and mapped liuslite.junit to
org.apache.tika
* I placed the other liusLite/src subfolders to src/main/java/org/apache/tika and mapped liuslite.*
to org.apache.tika.*
* I placed liusLite/config to src/main/resources
* I placed liusLite/testFiles to src/test/resources

Finally I used "svn add" to mark the new files for version control and used "svn diff" from
trunk to create the attached patch file.

Note that the patch is not ready for inclusion, as it doesn't change pom.xml to include all
the required dependencies. It should still help illustrate what I think the codebase should
look like.

> Hi,
> This is a work in progress of Lius. The release remove all Lucene dependencies and use
Nutch Office parsers because they are based on Apache POI.
> Lius Lite offer 4 ways  for content extraction :
> - Document fulltext extraction
> - XPath extraction
> - Regex extraction
> - Document metadata extraction (not implemented for all parsers)
> Lius Lite use an XML config file to configure the parsers and the information to extract.
 Please see config.xml in the config folder
> See also Junit tests.
> Here is an example  of XML parsing :
