Hi all,
This talk might have been seen by some of you; but was certainly new

Much of this is an exploration of how google is making use of
freebase's underlying linked data to better understand what they are
crawling - deriving what something is by examining its attributes; and
automatically creating something like linked data from it.
Additionally; it talks about Google squared - this tool appears to be
heavily powered by freebase data; as well as derived data from the
web. I was fairly impressed by the mix of understanding a user query
and rendering results as actual entities (one of the few non-facet
based UIs I have seen).
For instance: "territorial authorities in new zealand"
http://www.google.com/squared/search?q=territorial+authorities+in+new+zealand
Whilst this is not using the typical linked data technology stack of
RDF, SPARQL, open licenced data, etc; it certainly shows you what can
be done with data in a graph structure; plus a UI which is a cross
between a spreadsheet and a search result.
Daniel,
Export the tabular data, lookup URIs from DBpedia, add to table, use
angle brackets for URIs, de-normalize to 3-tuple structure (table with
Reference values), and you have platform agnostic Linked Data. This
resource can be ingested by anything that supports N-Triples :-)
Great example.
Of course folks can go down other unproductive routes, but be best
assured, the guide above gets you to the finishing line quickly. In
addition, it demonstrates the real power of Linked Data at InterWeb
scale without any platform lock-in.
The game of Linked Data isn't about Lock-In. It's about Open Access to
Linked Data Objects, leveraging the prowers of URIs as "Super Keys".
