This document is important for defining the 5 Stars of Linked Data. You can be well prepared for LAWDI by thinking about those stars or by being ready to ask questions about what they mean. It also belongs in the "Fundational Documents" below.
The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data.
This is a brief summary of last year's LAWDI. But let's not let the past influence this year's version too much...
“Now many people will tell you (indeed I probably will too) that you need to distinguish the statements you make about the thing in the real world from the statements about the document. For example, a URI for me might return a document with some information about me, but the creation date for that document and the creation date for me are two different things. And because you don’t want to get confused it’s better to have a URI for the thing and another one for the document making assertions about the thing. Make sense?”
“I agree that the really interesting assertions in Linked Data are about things, and their relations...”
This 40 minute plus video is for the more technically inclined. It is bracing by way of being frank about failures but is optimistic by way of pointing out where Linked Data is making progress. And the emphasis at the end on JSON-LD ( http://json-ld.org ) is useful.

Anecdotes about the relationship of the term "Resource" to "Document" and "Thing" and a nice synopsis of the W3C TAG's HTTPrange-14 finding. HTTPrange-14 changed (or hijacked, depending on your POV) the HTTP spec to segregate non-information resources (things) from information resources (documents).
