Object literal "Ora Lassila" In this document we will diagram an RDF statement pictorially using directed labeled graphs also called "nodes and arcs diagrams". In these diagrams, the nodes drawn as ovals represent resources and arcs represent named properties. Nodes that represent string literals will be drawn as rectangles.
The sentence above would thus be diagrammed as: Simple node and arc diagram Note: The direction of the arrow is important. The arc always starts at the subject and points to the object of the statement. The simple diagram above may also be read "http: Now, consider the case that we want to say something more about the characteristics of the creator of this resource.
In prose, such a sentence would be: The intention of this sentence is to make the value of the Creator property a structured entity.
In RDF such an entity is represented as another resource. The sentence above does not give a name to that resource; it is anonymous, so in the diagram below we represent it with an empty oval: Property with structured value Note: The structured entity of the previous example can also be assigned a unique identifier.
The choice of identifier is made by the application database designer. To continue the example, imagine that an employee id is used as the unique identifier for a "person" resource. The URIs that serve as the unique keys for each employee as defined by the organization might then be something like http: Now we can write the two sentences: The individual referred to by employee id is named Ora Lassila and has the email address lassila w3.
The RDF model for these sentences is: Structured value with identifier Note that this diagram is identical to the previous one with the addition of the URI for the previously anonymous resource.
From the point of view of a second application querying this model, there is no distinction between the statements made in a single sentence and the statements made in separate sentences.
Some applications will need to be able to make such a distinction however, and RDF supports this; see Section 4, Statements about Statementsfor further details.
A concrete syntax is also needed for the purposes of creating and exchanging this metadata. RDF also requires the XML namespace facility to precisely associate each property with the schema that defines the property; see Section 2.
The requirement that the property and type names in end-tags exactly match the names in the corresponding start-tags is implied by the XML rules.
All syntactic flexibilities of XML are also implicitly included; e. The serialization syntax expresses the full capabilities of the data model in a very regular fashion.
The abbreviated syntax includes additional constructs that provide a more compact form to represent a subset of the data model. RDF interpreters are expected to implement both the full serialization syntax and the abbreviated syntax. Consequently, metadata authors are free to mix the two.
Basic Serialization Syntax A single RDF statement seldom appears in isolation; most commonly several properties of a resource will be given together.
The Description element names, in an about attribute, the resource to which each of the statements apply. If the resource does not yet exist i. Basic RDF serialization syntax takes the form: Description contains the remaining elements that cause the creation of statements in the model instance.
The Description element may be thought of for purposes of the basic RDF syntax as simply a place to hold the identification of the resource being described. Typically there will be more than one statement made about a resource; Description provides a way to give the resource name just once for several statements.
When the about attribute is specified with Description, the statements in the Description refer to the resource whose identifier is determined from the about. The corresponding resource identifier is obtained by resolving the URI-reference to absolute form as specified by [URI].
If a fragment identifier is included in the URI-reference then the resource identifier refers only to the subcomponent of the containing resource that is identifed by the corresponding fragment id internal to that containing resource see anchor in [ Dexter94 ]otherwise the identifier refers to the entire resource specified by the URI.
A Description element without an about attribute represents a new resource.Competitors of Nokia Corporation Nokia’s direct and major competitors include Motorola Inc, Cisco Systems Inc, Research in Motion, LM Ericsson Telephone Co., and QUALCOMM Inc.
