One little correction. Please change: Virtuoso Sponger (the name of a 
component of Virtuoso) [1] to URIBurner (an actual service that 
generates HTTP based Linked Data "on the fly" from a myriad of Web 
accessible Resource Types, and persist into a Quad Store) [2][3].

Everytime a user invokes the services of URIBurner (via Bookmarklet or 
extensions re. FF) the following happens:

1. Resource is RDFized (this is a pipeline that includes making a basic 
graph from target resource and the performing LOD cloud lookups en route 
to making a richer Linked Data mesh)
2. Data Objects re assigned proxy HTTP URIs (Linked Data principles 
3. owl:sameAs relations are established with the RDFized Resource (Rule 
4, in a nutshell)

Net effects of the above:

1. Powerful Linked Data meshes that are reusable across any HTTP network 
(Data Object HTTP URI is all you need)
2. Discovery can occur via HTML pages (which use <head/> and <link/>  
for auto-discovery) or via HTTP response via LINK header (matching 
what's in the HTML <head/> re. <link/>
3. URI Discovery can also occur via the /FCT (Faceted Browser Service) 
which offers: Full Text, URI Lookup by Label, and raw URI Lookups
4. URI Discovery can also occur via Usage Pages associated with this 
instance (or any other Virtuoso instance with /FCT enabled) which 
expose: Direct and In-direct co-references
5. SPARQL endpoint which is Sponger Enabled (so you can query what's in 
there or provide Resource URLs as Graph IRIs and progressive add more to 
the Quad Store)
6. Progressive increments to the LOD cloud based on user interactions 
means we have a dynamic component to the LOD cloud that goes beyond data 
sets loaded into RDF stores.

Chris/Anja: The same comment applies to the next edition of the LOD 
cloud re.  Sponger label.
