To make some publicity here... There will be a LOD Camp at the WWW2010 in Raleigh, NC:


a good place where at least some of the work started by Juan and friends can be pursued!

> This has been my concern from day one! And day one from me was when I attended the Publishing Linked Data tutorial [1] at ISWC2008! It wasn't clear to me what you could do with Linked Data, for a web developer perspective. However, then I saw the Semantic Web Client Library [2] and then it hit me: Linked Data makes the web appear as one giant database. This is when Olaf Hartig and I started talking and we created SQUIN [3]. The motivation was that there isn't an easy way to query the existing Linked Data on the web. This opened a new problem that has never been faced before (query execution on a web of linked data), which Olaf has started to tackle [4] and so are we.
> Because ISWC2008 had the publishing linked data tutorial, Olaf Hartig, Patrick Sinclair (BBC), Jamie Taylor (Freebase) and I thought that ISWC2009 should have the consuming linked data tutorial. In the process of organizing the tutorial, we realized that there isn't an organized way of consuming linked data, hence the lack of linked data apps (apps that consume linked data). So there is a need to tell people 1) what you can do with linked data and 2) how you can do it! Hopefully our slides will help:

> However, a few weeks before ISWC2009, I posted a question about consuming linked data apps and that we should get together during the conference and hack up some apps. The whole idea grew and I organized in a few days the 1st Linked Data-a-thon which was held at ISWC2009 (www.linkeddata-a-thon.com)  The objective was to hack-up consuming linked data apps. Honestly, this was kind of selfish of me :) I have a lot of web developer friends who I talk to about Linked Data.. but I have no real online apps to show off the power of Linked Data. With the apps created during the Linked Data-a-thon, I can now go show off and tell people the types of things that can be done. During this event, everybody learned a lot. We learned about the current status of Linked Data, the tools, infrastructure, what it takes to do a linked data app, what was easy, what was hard. Several participants and I got together and wrote up a document. We have this on hold but I will now push this so we can at least publish it as a blog post and share with the whole community our lessons learned. Some experiences can be found on the linked data-a-thon website or here [5].
> In summary, everybody on this list should go build their own Consuming Linked Data app! Hopefully before April 26... so when we present the tutorial again, we will have much more apps to show off!
