Examples of XRI Cross-reference Syntax
Say a library system uses URNs in the ISBN namespace to identify books and DNS subdomains to identify its library branches. HTTP URI syntax does not provide a standard way to express the URN for the book title in the context of the DNS name for the library branch. XRI cross-reference syntax solves this problem by allowing the library (and even automated programs running at the library) to programmatically construct the XRIs necessary to address any book at any branch. Examples:
xri://broadview.library.example.com/(urn:isbn:0-395-36341-1) xri://shoreline.library.example.com/(urn:isbn:0-395-36341-1) xri://northgate.library.example.com/(urn:isbn:0-395-36341-1)This ability to create structured, self-describing identifiers can be extended to many other uses. For example, say the library wanted to indicate the type of each book available. By establishing a simple XRI dictionary of book types, it can now programmatically construct XRIs that include this metadata,
xri://broadview.library.example.com/(urn:isbn:0-395-36341-1)/(+hardcover) xri://broadview.library.example.com/(urn:isbn:0-395-36341-1)/(+softcover) xri://broadview.library.example.com/(urn:isbn:0-395-36341-1)/(+reference)Read more about this topic: XRI
