In an attempt to "kill many birds with a single stone" here is a #swig 
logger session link 
<http://chatlogs.planetrdf.com/swig/2008-06-22#T20-23-40> covering the 
thinking behind a new extension re. are realising for Firefox 2.x and 
3.x (of course other browsers to follow).

Gist of the matter:
We are adding: View | Linked Data Sources, to browsers, so that Linked 
Data is revealed to Web Users as the 3rd  of the following options:

1. View Rendered Page (what you get by default)
2. View Page Source (how you look at the markup behind the page)
3. View Linked Data Sources (how you look at the raw data behind the 
page; the data the page puts in context in rendered form)

Of course, the same applies to the Browser Context Menus, meaning: 
"Linked Data Sources" occurs as an option (for completeness this will be 
changed to: "View Linked Data Sources").

Our extension uses an HTTP Proxy (Sponger) which is associated with 
RDFizers (think of these as RDF analogs of ODBC/JDBC Drivers, but for 
Web Data). Thus, you can increase or decrease the quality of the linked 
data graph via the Cartridges/Drivers that you plug into your data spaces.

Also note, the recent enhancement to Semantic Radar now makes it 
possible to incorporate Linked Data Browsers/Viewers from a myriad of 
providers (OpenLink, Zitgist, Marbles, DISCO, Tabulator etc.), which is 
great, but you will note that the new plugin doesn't mandate any 
discovery of RDF. It simply takes a URL and then RDfizes it whenever you 
take the: "View | Linked Data Sources" menu or context menu route.

The initial cut of the extension is at:

Of course, there are a few updates on the way later this week(mostly 
aesthetic bar the non functioning "Search" feature). That said, you can 
get to the essence of what I am talking about via the initial release.


   1. My Linked Data Planet Keynote
      (thanks to RDFa and the Bibliographic Ontology it's now possible
      to model Presentations (Slideshows) )
   2. Other Slidy Presentations from OpenLink
      <http://virtuoso.openlinksw.com/Whitepapers/index.htm> enhanced
      with RDFa annotations.

Final note: since we already have a Cartridge/Driver for Slidy based 
data sources, you can also view the data behind any Slidy presentation. 
Of course, the context fidelity of the graph would be low (i.e. low 
linked data resolution) without RDFa or some other Linked Data exposure 
mechanism, but if you have a meta cartridge (e.g. the kind that Zitgist 
delivers via it's exploitation of UMBEL aided Named Entity Extraction 
and Disambiguation), you don't even require RDFa en route to context 
fidelity (HIgh Def. Linked Data), you just slot that cartridge into your 
data space.

BTW - http://community.linkeddata.org/ods remains open to community 
members seeking both a data space and an easy place to get an Entity URI :-)
