This is the original idea of the Solr plugin.

It will be pretty simple. You will have to define a SIREn field type 
with the SIREn analyzer, and then use the field type for creating SIREn 
fields.
For the query parser, you will have to register the solr parser plugin 
in the solrconfig.xml.
I will update the documentation, and add a Solr demo (with a schema.xml 
and solrconfig.xml preconfigured) when the Solr plugin will be released.

Could you develop your idea ?

There is two others projects that I know. The first one is from 
Frederick Giasson [1]. It is not a plugin / extension of Lucene / Solr, 
it is more a way to create a Solr schema that partially encodes the RDF 
data structure. The second one is a Google Summer of Code project [2] (I 
was co-mentor of the project), but it is not yet stable.

We'll do our best to deliver the plugin quickly ;o).
