Well, let's take Eric's example:
> <book id="book_0805033106">
> <isbn>0805033106</isbn>
> <title>Peanuts Every Sunday </title>
> <author href="author_Charles-M.-Schulz"/>
> <character href="character_Sally-Brown"/>
> <character href="character_Snoopy"/>
> <character href="character_Linus"/>
> <character href="character_Lucy"/>
> </book>
Assuming that id is changed to rdf:id, and that a relevant namespace
declaration appears somewhere for the null prefix (RDF doesn't like
elements without namespaces), then an RDF processor can discover that:
There is a type named "book";
There is an object of type "book" whose ID is "book_0805033106";
The book has the "isbn" property with value "0805033106";
The book has the "title" property with value "Peanuts Every Sunday";
The book has the "author" property with value anonymous-1;
Anonymous-1 has the "href" property with value "author_Charles-M.-Schulz"
The book has the "character" property with value anonymous-2;
Anonymous-2 has the "character" property with value "character_Sally-Brown";
Etc.
By changing the "href" attributes to "rdf:resource" attributes, we remove
part of the indirection, and get:
The book has the "author" property with value the resource identified by
the URI "author_Charles-M.-Schulz";
The book has the "character" property with value the resource identified by
the URI "character_Sally_Brown";
Etc.
