Frederick Giasson penned
an interesting post earlier today that highlighted the RDF
Middleware services offered by
Triplr and the Virtuoso Sponger
Some Definitions (as per usual):
RDF Middleware (as defined in this context) is about producing
RDF from non RDF Data Sources. This implies that you can use non
RDF Data Sources (e.g. (X)HTML Web Pages, (X)HTML Web Pages hosting
Microformats, and even Web Services such as those from Google,
Del.icio.us, Flickr etc..) as Semantic Web Data Source URIs
(pointers to RDF Data).
In this post I would like to provide a similar perspective on
this ability to treat non RDF as RDF from RDF Browser
First off, what's an RDF Browser?
An RDF Browser is a piece of technology that enables you to
RDF Data Sources by way of Data Link Traversal. The key
difference between this approach and traditional browsing is that
Data Links are typed (they possess inherent meaning and context)
whereas traditional links are untyped (although universally we have
been trained to type them as links to Blurb in the form of (X)HTML
pages or what is popularly called "Web Content".).
There are a number of RDF Browsers that I am aware off (note:
pop me a message directly of by way of a comment to this post if
you have a browser that I am unaware of), and they include (in
order of creation and availability):
Each of the browsers above can consume the services of Triplr or
the Virtuoso Sponger en route to unveiling a RDF Data that is
traversable via URI
dereferencing (HTTP GETing the data exposed by the Data
Pointer). Thus you can cut&paste the following into each of the
aforementioned RDF Browsers:
Since we are all time challenged (naturally!) you can also just
click on these permalinks for the OAT RDF Browser demos:

This document is empty and basically useless. It is generated by a web service that can make some statements in HTML Microdata format.
This time the service made zero such statements, sorry.
