    most excellent except for the conspicuous absence of the 'obligatory obama slide' :-)

Notes on slide 1

I’m a long time non-coding contributor. Founder of Bryght, organizer of many past Drupal events, and permanent member of the Drupal Association.

Current day job is Bootup Labs, incubating startups in Vancouver, BC

Not going to really cover Calais - it’s a great way to add semantic links to data as you create it. Mainly talk about bottom up usage

The ! is because I’m excited

Is the spending data on recovery.gov available in a format (like XML) that developers can use to create mashups and gadgets?
A: Not at this time. But, as new systems are developed to capture the allocations and expenditures under the Act, we plan to make that data available in exportable form.

The goal of the W3C SWEO Linking Open Data community project is to extend the Web with a data commons by publishing various open data sets as RDF on the Web and by setting RDF links between data items from different data sources.

RDF links enable you to navigate from a data item within one data source to related data items within other sources using a Semantic Web browser. RDF links can also be followed by the crawlers of Semantic Web search engines, which may provide sophisticated search and query capabilities over crawled data. As query results are structured data and not just links to HTML pages, they can be used within other applications.

The figures below show the data sets that have been published and interlinked by the project so far. Collectively, the data sets consist of over two billion RDF triples, which are interlinked by around 3 million RDF links (October 2007).

There is a patch for Flickr querying
SPARQL is like SQL for semantic data -- queries across the web







All in D6, today
RDF etc. -- I shouldn’t say etc., because there is a ton there today
MOAT -- been trying to do this forever, this is a real use case
Exhibit -- easier tools are always good

So, what do we include in core? what is useful and practical out of the box?

  27. Recovery.gov Saturday, March 7, 2009
  28. Apps for Democracy: District CTO Vivek Kundra “While the immediate goal of the Applications for Democracy contest is to develop innovative software to present District data, its long-term goals are broader,” said District CTO Vivek Kundra. “By making government data easy for everyone to access and use, the District hopes to foster citizen participation in government, drive private-sector technology innovation and growth, and build a new model for government-private sector collaboration that can help all governments address the technology challenges of today and tomorrow.” Saturday, March 7, 2009

  35. Processing is moving Past: Move the data to where the processing is Future: Move the processing to where the data is Saturday, March 7, 2009
  36. Amazon gives away free TB Amazon is storing public datasets - over 1 TB of data It actually saves them money, but it also makes their customers’ applications faster (processing next to data) Trevor O: if other hosting companies did this, then if even 2 people used it, they would save money - moving data across the LAN is cheaper than across the WAN Saturday, March 7, 2009
  37. Read Write Web on Amazon Public Data Sets You've read, or can imagine, the impact that the first Public Libraries had on human culture. Now imagine the opening up of not just this, but other libraries of data, so huge that economies of scale blast the project off beyond any analogy that could be drawn with our everyday experience or historical memories. It won't just be Amazon that offers up this kind of data - it will be relatively commonplace soon, we imagine. It will be like a network of libraries - for robots. Robots that go to the library frequently, read very fast and make serious use of what they've learned. Saturday, March 7, 2009
  38. Where does Drupal come in? Saturday, March 7, 2009
  39. Drupal is getting semantic Looks to be the first general purpose CMS that has significant semantic data out of the box If we ship Drupal 7 with semantic data turned on out of the box (i.e. content you create is automatically marked up), will probably be the most widely deployed semantic platform 200K downloads / month plus lots of people creating content = lots of semantic data from the bottom up Saturday, March 7, 2009
  40. Linking Open Data …the data sets consist of over two billion RDF triples, which are interlinked by around 3 million RDF links (Oct. 2007) Saturday, March 7, 2009

  51. Views across the Web Remember the first time you had your mind blown when building views? What if you could operate on any data, anywhere on the web, with a similar interface? That’s why you should care about the Semantic Web - it enables this This is where I mention SPARQL Saturday, March 7, 2009

  63. Mission: Possible Dries said “Every movement needs a mission” Drupal’s mission is to help evolve the web Saturday, March 7, 2009
  64. How do we do it? We pioneered aggregation, multi user blogging, taxonomy and more on a platform that runs anywhere Help make Drupal 7 the first semantic enabled CMS Not just “the first” - but the one that just works, while you’re building powerful, usable sites Saturday, March 7, 2009
