Note: Slides from the SWS Metadata lecture
Think of your favourite book. If you can't think of one, pick something off the SWS reading list.
Take a look at the Dublin Core documentation and the Guidelines for encoding bibliographic information with Dublin Core.
Write down as much metadata about your book as possible using Dublin Core terms, and note the Dublin Core namespaces you use. Use as many properties as possible. Eg. (this example uses a only small subset of possible properties):
Namespaces:
| Dublin Core term | Value |
|---|---|
| dc:title | "Weaving the Web: The Original Design and Ultimate Destiny of the World Wide Web by its inventor" |
| dc:creator | "Tim Berners-Lee" |
| dc:type | dctype:PhysicalObject |
| dc:publisher | "Harper Publications" |
| ... | "..." |
Look through your metadata and identify entities that ought to have a unique identifier of their own, not forgetting the book itself. Create a unique identifier (ie. URI) for your book; you can make up your own, or see if you can find it somewhere like DBPedia. Replace other values that are strings (aka Literals) with URIs as appropriate, eg (the following is in the Turtle syntax of RDF):
@prefix dc: <http://purl.org/dc/terms/creator/> .
@prefix dctype: <http://purl.org/dc/dcmitype/> .
<http://dbpedia.org/resource/Weaving_the_Web> dc:title "Weaving the Web: The Original Design and Ultimate Destiny of the World Wide Web by its inventor" .
<http://dbpedia.org/resource/Weaving_the_Web> dc:creator <http://www.w3.org/People/Berners-Lee/card#i> .
<http://dbpedia.org/resource/Weaving_the_Web> dc:type <dctype:PhysicalObject> .
<http://dbpedia.org/resource/Weaving_the_Web> dc:publisher <http://dbpedia.org/resource/Harper_(publisher)> .
Save your turtle in a file called book.ttl and publish it in your UoE webspace by copying it in the /public/homepages/<user>/web folder on your DICE machine. Now when you visit http://homepages.inf.ed.ac.uk/your-student-id/book.ttl you'll see your triples (although some browsers will try to force you to download the file, or you might have to try 'view-source' to see the output).
Validate your turtle to check it is syntactically correct. There are many validators, you could try this one ('translate' from N3 to N3). Fix any syntax errors that may occur.
Note about DBPedia URIs: When you visit a DBPedia URI you are redirect to a /page/ address. This is the URI for the webpage, not the thing the page is about. Use /resource/ in place of /page/ for the URI of the thing.
