A defining characteristic of the Data Web (Context Oriented Web
3.0) is that it facilitates Meshups rather than Mashups.
Reasons for the distinction:
So what? You may be thinking.
For starters, I can quite easily Mesh data from Googlebase
(which emits RSS 2.0 or Atom) and other data sources with the
Mapping Services from Yahoo!
I can achieve this in minutes without writing a single line of
code. I can do it because of the Data Model prowess of RDF
(self-describing instance-data), the data interchange and
transformation power of XML and XSLT respectively, the inherent
power of XML based Web Services (REST or SOAP), and of course,
having a Hybrid Server product like Virtuoso
at my disposal that delivers a cross platform solution for
exploiting all of these standards coherently.
I can share the self-describing describing data source that
serves my Meshup. Try reusing the data presented by a Mashup via
the same URL that you used to locate Mashup to get my drift.
What does this all mean?
"Context" is the catalyst of the burgeoning Data Web (Semantic
Web Layer - 1). It's the emerging appreciation of
"Context" that is driving the growing desire to increment Web
versions from 2.0 to 3.0. It also the the very same "Context" that
has been a preoccupation of Semantic Web vision since
The journey towards a more Semantic Web is all inclusive (all
"ANDs" and no "ORs" re. participation).
The Semantic Web is self-annotating.
Web 2.0 has provided a huge contribution to the self annotation
effort: on the Web we now have Data Spaces for Bookmarks (e.g
del.icio.us), Image Galleries ( e.g Flickr), Discussion Forums
(remember those comments associated with blog posts? ditto the
pingbacks and trackbacks?), People Profiles (FOAF, XFN,
del.icio.us, and those crumbling walled-gardens around many Social
Networks), and more..
A Web without granular access to Data is simply not a Web worth
having (think about the menace of click-fraud and spam).

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.
