- 25. The record is nothing but the content of its fields, just as an RDF node is nothing but the connections: the property values. The mapping is very direct * a record is an RDF node; * the field (column) name is RDF propertyType; and * the record field (table cell) is a value. Indeed, one of the main driving forces for the Semantic web, has always been the expression, on the Web, of the vast amount of relational database information in a way that can be processsed by machines.

- 26. URI ⊇ Primary/Foreign Keys shared innovation ™
- 27. Using natural keys is the traditional approach, in line with Codd's original relational model. When you use them, you have only natural data that means something to users. This is good if users will ask ad hoc queries directly to the database in raw SQL. You can also often reduce the numbers of joins when using natural keys because you don't have to go to a lookup table to convert an ID to a description.

- 28. The fundamental issue is that keys are a significant source of coupling within a relational schema, and as a result they are difficult to change. The implication is that you generally want to avoid keys with business meaning because business meaning changes. Choosing a Primary Key: Natural or Surrogate?

Editor's Notes
- #3: Final copy is in the proceedings of WWW2008.
- #9: It's running off this stuff We do a bit of work to it... Looking at it this makes my eyes go fuzzy
- #10: Is that better? What we do is we keep the field data...
- #11: We've done work on leader elements, indicators and fixed format fields, but today to keep things simple I'm just taking basic field data. Let's throw the rest away for now.
- #12: When you see white boxes like this I mean that the data model contains literal text strings. Let's move them around a bit to make space for something.
- #14: Because we're describing the thing the record was about, rather than the record itself, we can use different labels. Let's take just one of these relationships
- #15: The problem becomes clear if we move something out of the way, to make room for something else.
- #16: Something else has a title of "harry potter and the order of the phoenix" Unsurprisingly, something and something else have a lot in common
- #17: This approach is what I would call record-centric, we haven't got any more meaning than was in the original record. Let's talk that through as an example [click] The two books are both by JK Rowling, but this is not JK Rowling, this is a string of text. This is JK Rowling...
- #18: OK, so it's not JK Rowling, it's a picture of JK Rowling - I asked, but she wouldn't come. The point is that the words Rowling, JK and the author known as JK Rowling are different things Not a new thought I know...
- #19: This man made great use of new technology back in the 1800s, he represented authors, titles and subjects as abstract concepts, with each author being recognised even if they shared the same name. Subjects were recognised as different even if they shared common terms and more. He wrote about it
- #20: In this great book - anyone read it? The technology he was taking advantage of?
- #21: The card... What I'm trying to do with the data is not really different to the introduction of card catalogs over bound volumes So, let's get back to the present day...
- #22: Focussing on JK for the moment, let's throw the rest away
- #23: Remember I said a resource could represent anything? well, let's use one to represent the author...
- #24: Let's get rid of the strings, and just leave the concepts, that makes things look simpler. Now, one of the things that has gone unsaid so far is that something and something else came from monograph records, so we know that they are both books.
- #25: dbpedia, geonames (Embrun, France), CIA Factbook, MusicBrainz/Zitgist (Diana Ross), DBLP (Advances in Orthonormalizing Computation.), RDF BookMashup (Weaving the Web), RDF BookMashup
- #27: URI is a superset of what we can do with Primary keys
- #31: We take the data elements
- #32: We take the data elements
- #35: Take the algorithms used for lookups Turn them around to make hashes Keep the essence of the natural data Discard syntactic differences If too long (or you like GUIDs) MD5 them.
- #43: * Stardust (novel), an illustrated novel by Neil Gaiman and Charles Vess * Stardust (2007 film), the film adaptation of the above book * Stardust (1990 novel), a 1990 novel by Robert B. Parker * Stardust (1974 film), a film about a rock star, starring David Essex. * Stardust (1940 film), a film with Linda Darnell and John Payne * Stardust (game), a shoot 'em up computer game * Stardust (magazine), a popular Indian film magazine
