Hello,

I need reification in gnowsis.org, so I wonder:

- What is the recommended way to do reification in RDF/XML?

- When I want to reify masses of statements (f.e. using Jena) the 
storage space explodes (when using plaintext RDF/XML files). This is 
awful, as reification would be real useful sometimes. Any best practice?

- What about reifcation in N3?
The spec(?) says:
http://www.w3.org/DesignIssues/Notation3.html

Notation3, of any level, can be represneted as an RDF graph using a 
vocabulary |<http://www.w3.org/2004/06/rei#>|. Code exists (|cwm 
--reify| and |cwm --dereify|) to convert N3 to such a description and 
back. This allows, for example, rule files to be manipulated as RDF data.

This reification also allows an RDF graph to be described, quoted, 
within another RDF graph. (Note that the "reification" described in the 
*RDF 1.0 specification is different, doe snot quote properly, and is not 
recommended.*)


so- what does this mean?


any help appreciated.

cheers
Leo

come out :-)
