BASED ON A SHOW of hands, Salim Ismail addressed an IT@Cork audience who were sitting on the shoreline of internet 3.0. Blogs are the first manifestation of the publish/subsribe paradigm. Ismail sees an event-based environment emerging across both enterprise and consumer space that opens up the hidden web, reduces the cost of starting a new business and threatens the current model of venture capital financing. "We have entered the third decade of the internet already. It is text-based, structures its data and is event-based along the publish/subscribe model".
Dave Winer wrote about an exciting dimension of structured data when he speculated about ways to syndicate Google spreadsheets by linking data via XML-RPC. John Robb has an idea for another "simple format, like RSS is for new post summaries, also be built for data. That would allow me to pick the data I want from a buffet of data and plug it into a spreadsheet."
I like using services that grab useful data from online repositories--like Flickrlilli--the search engine interface that allows you to search the Flickr photo database by any combination of Creative Commons license types. You can search for images by tag and sort results by date or interestingness.
At the Microlearning Conference running parallel to the IT@Cork event this week, Thomas Vander Wal spoke about three subjects that use structured data as foundation elements: The Come to Me Web and Personal InfoCloud subjects are covered in his website, along with folksonomy.
