Re: web to semantic web : an automated approach

Hi,

it's all happening, but it's not so easy as one may think in the first  
place.

Basically there are multiple sources of structured/interlinked  
information (A) and multiple ways of how to expose (B) linked data on  
the Web.

(A)
1. generated (wrapped) from information systems (RDBMS, etc) => needs  
mapping
2. user-generated (natively RDF-based systems, Semantic Wikis, etc.)  
=> already in the right form
3. extracted (AI, heuristics, cypher, etc. - different levels of  
granularity; difficult, sometimes wrong)

(B)
1. RDF documents
2. SPARQL endpoints
3. embedded into HTML (RDFa)

The Linked Data Community project plays an important role regarding A1  
and A2. A3 is cumbersome and may produce wrong links and information -  
a nightmare without implicit support for provenance. In corporate  
environments A3 is already very popular, but in the broader Web-scale  
I'm a bit sceptical this will work well. What do you tink?

Regards,
AndyL
