Many thanks, Kingsley.
Two questions, just to confirm my understanding of the instructions below:
1. On #3, do you mean append /sparql to the path in #2? For example are
you saying the full URI in the browser address window would then be
http://localhost:8890/about/html/<URL-of-XHTML-with-RDFa-resource>/sparql
No: http://linkeddata.uriburner.com/about/html/http://tobyinkster.co.uk/
This URI does produce a page with the title
About:<URL-of-XHTML-with-RDFa-resource>/sparql
2. If #1 is correct above, the page above has an empty table of
properties and values, but no indication of where to change the graph
IRI. Could you be more specific on #4?
Then SPARQL at: http://linkeddata.uriburner.com/sparl using the
following Graph IRI in FROM: http://tobyinkster.co.uk/
e.g.
select distinct * from <http://tobyinkster.co.uk/> where {?s ?p ?o}
The sponger provides a progressive mechanism for populating the Virtuoso
Quad store.
Thus, if you get: http://ode.openlinksw.com, you can use the config
options to bind it to your own Virtuoso instance, then when you do:
- View | Page Description
- View | Linked Data Sources
You actually create triples in the Quad Store with Graph IRIs derived
from the source URLs of the sponged resources :-)

Hello Virtuosi:
I'm up and running. The build was great on OpenSolaris 2008.11.
I would like to import a valid XHTML+RDFa file. I already have the
file. Would you happen to have a pointer to how to run an import?
Thanking you in advance for your help and such a wonderful product!
Thanks for the warm compliments :-)
The easiest route for getting Triples from HTML+RDFa is to sponge the
resource.
This means:
1. installing the mappers_dav.vad package --- this holds all the sponger
cartridges (RDFizers)
2. Enter the following into your browser:
http://<cname>/about/html/<URL-of-XHTML-with-RDFa-resource>
3. Go to /sparql
4. Change the default GRAPH IRI (Data Source URL value) to:
<URL-of-XHTML-with-RDFa-resource>
5. You should see all the RDFa triples .
