What are the issues in indexing rdf? I would be interested to see a discusion of this. Off the top of my head it would be one thing to index the data, regardless of enclosing tags, but something else to employ the tags as adjunct to the index. Has this been approached anywhere? A third part would be pure indexing of the tags only - I wonder if there would be any use for this, but suspect there would for optimisation and to help guide querries, for instance there would be no sense in searching for content that would only be surrounded by tags that don't exist in the document instances being inspected and, conversely, there maybe a lot of sense in searching where the tag appears frequently, or because of some other logical or statistical property of the tag. As far as i have researched this I know that the gnowsis project uses both rdf and lucene, but I have not had time to determine their relationship. www.gnowsis.org/ DSpace <http://www.dspace.org/> also supports a lucene interface but, again, I don't know how it is used.

I used java libraries for rtf file formats. Refer to Mannning's Lucene In Action book.
