4. Differents in function extended from "RDF primer" RDF primer: This specification: Mainly talked about the base concept and idea in use literal, resource, node, blank node, property, xmlns, URI. etc... Mainly talked about the simple document construction an formwork the child element of an ancestor element,etc... And talked about various ways to abbreviate the syntax to make property [rdf:type],and so on... New concept built for descrbing the syntax construcion will be given More essential defination of the document construction will be given More methods to make document concise will be introduced

5. The essential of the RDF construction given 1-fundational thought "route": 2-method to abbreviate: Any complete RDF graph is made up by several "route". The RDF document is stating these routes in order from the top to the bottom of the document. abbr. makes the document conciser, more human-readable, and more flexible. Of course, this may confuse the beginners.

8. Concept mentioned in RDF rdf:nodeID rdf:ID rdf:Description rdf:RDF rdf:type rdf:datatype rdf:about rdf:Resource a necessary tag when use RDF to give URIref of subject resource to start a statement of resource addtion information of typed Literal to mark a Uname node state resource with relative URIref this resource is instance of class K E Y W O R D S to give URIref of property value

9. Concept for descibing the struction empty Element Property Element Property Attributes Node Element A element representing an arc in graph A property and its value apear as attribute of a Node Element instead of apearing as a "Property Element" a element without text between tags K E Y W O R D S A element representing a node in graph Essentially a format to abbreviate the property with literal whose value is literal instead of resource Literal Excluded

11. Omit Technology Basic technology: abbreviate the different routes which have the same trunk: route 1: a_b_c_d1 route 2: a_b_c_d2 this is essentially route Mode (property element is omitted) Omitted:

12. other omit technology: I. Empty property elements II. Property Attributes III. Property Attributes on empty Property Element IV. Reifying Statements Omit Technology
