All,
Quick note re. the Firefox Linked Data Sources extension ( "rdfb.xpi") :
1. Download to your local filesystem
2. Use File | Open from Firefox to load (this isn't a properly signed
XPI at the current time)
Kingsley
All,
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:
http://myopenlink.net:8890/~kidehen/Public/rdfb.xpi
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.

(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 :-)
