Indexed Files Activities Extension Pack
=======================================

This Extension Pack adds file indexing functionality to existing
deployments of OGSA-DAI 3.1. This functionality will be incorporated
into the next release of OGSA-DAI but it is released here so that it
may be used with OGSA-DAI 3.1.

The pack adds four activities that use Apache Lucene
(http://lucene.apache.org) to provide indexing and search capabilities
to OGSA-DAI 3.1. The four activities are:

 o CreateAnalyzer  - instantiates a Lucene Analyzer Object (removes funny
                     characters and converts input to lower case).
 o CreateMapper    - instantiates an OGSA-DAI mapper which provides the
                     indexing algorithm for a specific type of file.
 o CreateFileIndex - applies an indexing mechanism to a file.
 o LookupIndexFile - performs a query over an index using the Apache 
                     Lucene full-text search engine. 

Documentation is included in the extension pack.
