[iks-community] Help on Semantic Search

[Axel Polleres]

Hi all

May I kindly ask the IKS community for support here:

I briefly talked to John about the possiblity to turn this initial  
proposal into a small Demo.
In order to come up with some test-data to crawl and search and  
provide a Demo...

Could any of you running Drupal sites install and enable the basic RDF/ 
CCK module [1]
and let us know the URL of your site. What this module does is  
exporting the gist of your
CCK content model as RDF such that we could "semantically crawl" and  
index
your site in for our search demo! Please get back to us if you need  
assistance.

Thanks and best regards,
Axel
