[edit] snipped from Part 1

[edit] URI

Uniform Resource Identifier

global names for:

• documents
• things
• relationships between things

Definition of a resource: anything that can be identified with a URI

[edit] HTTP

Hypertext Transfer Protocol

provides access to URI-named documents

[edit] Formats

• HTML
• XML
• other text formats
• binary formats : images, sounds, proprietary document formats
• RDF formats : RDF/XML, Turtle, eRDF, RDFa, anything GRDDLable etc.

- all potentially URI-identified documents for HTTP

[edit] RDF

Resource Description Framework

Data model based on:

• URIs for things
• URIs for relationships between things

[edit] Links

References to other URIs in URI-identified documents:

• HTML links
• RDF properties - out-of-band links between subject-object resources
• links in other formats (e.g. rss:channel)

URIs + document formats enable links

links + HTTP enable "the basic follow-your-nose way the web works"

http://www.w3.org/DesignIssues/diagrams/arch/follow.png - scary!

[edit] SPARQL

Sparql Protocol and RDF Query Language

SQL-like query language, works over RDF data

[edit] Other Technologies

• operating systems
• HTTP servers, browsers
• programming language of you choice (here PHP)
• tools for RDF - ??
• tools for XML - XSLT...
