This document discusses different ways that humans can consume linked data on the web. It describes HTML browsers that can render RDFa embedded in web pages. It also discusses linked data browsers that allow users to view RDF triples in a tabular format. Faceted browsers provide a way to explore linked data through interactive facets. On-the-fly mashups dynamically combine data from multiple sources. The document encourages the development of new and innovative interfaces for interacting with linked data.

Browsers
• RDF
can
be
serialized
in
RDFa
• Have
you
heard
of
– Yahoo’s
Search
Monkey
– Google
Rich
Snippets?
• They
are
consuming
RDFa
• But
WHY?

7. Because
there
is
life
beyond

9. Google
and
Yahoo
are
starRng
to
crawl
RDFa!
The

Web
is
a
reality!

10. The
Reality
• Yahoo
is
crawling
data
that
is
in
RDFa
and
Microformats
under
a
specific
vocabularies

• Google
is
crawling
RDFa
and
Microformats
that
use
the
Google
vocabulary
• How
much
of
this
is
Linked
Data
– I
don’t
know
