Do explore the service at: http://lod.openlinksw.com ? Take note of the 3 tabs on the home page. Also note the VoiD graph at: http://lod.openlinksw.com/void/Dataset, meaning you can even start exploring the LOD cloud from the description of a dataset. > Hopefully tomorrow's session we will come up with interesting > solutions. Currently, you need to know the URI (unfortunately). No you don't. Take a look at "URI Lookup (by Label)" tab. Type in a literal pattern associated with an Entity who's URI you seek. > Same thing follows for the other problem. Right now, you need to know > the datasets and what vocabularies to use.

Yes, I am assuming Orri Erling made this crystal clear during his workshop talk. Otherwise, do try catching up with him if you can.
