Now there is a great pitch line!
“the site allows users to upload data – any data – and display it to other users visually. … Uploaded data can be rated, commented and bookmarked by other users, helping to sort the interesting (and accurate) wheat from the chaff. And graphs of data can be embedded into websites. So it is in fact a bit like a YouTube for Data. But then the real fun begins. You and other users can then compare that data to other data sets to find possible correlation (or lack thereof).”
Here’s the business model, according to TechCrunch — Swivel will provide a free service public data and charge a fee for data that is kept private.
I’m anxious to see their data model and to compare it to an RDF approach. I suspect that Swivel does not provide a way to annotate the data with semantic information, so any correlations will have to be driven by people. There is a lot of room for the Semantic Web to contribute to this kind of system.
