URIs

Since an understanding of urirefs is central to working with RDF, we’ll take a moment to look at what makes a valid URI—the identifiers contained within a uriref and used to identify specific predicates.

Resources can be accessed with different protocols and using different syntaxes, such as using http:// to access a resource as a web page and ftp:// to access another resource using FTP. However, one thing each approach shares is the need to access a specific object given a unique name or identifier. URIs provide a common syntax for naming a resource regardless of the protocol used to access the resource. Best of all, the syntax can be extended to meet new needs and include new protocols.
