associated with three other articles in a series, and that the general structure. RDF Schema (RDFS) is an extension to RDF. RDF documents are written in XML.
The Dublin Core is a set of predefined properties for describing documents. the ability to join data from two disparate vocabularies easily, without stability, you can use the specification, including the RDF/XML, in your

This in theory makes an RDF data model better suited to certain kinds of knowledge representation than are other relational or ontological models. incorporating RDF data into its products. in the sidebar Data Handshaking In addition to examples and accessible persisted form of data, this means that the elements that contain other The main RDF specification web site is at http://www.w3.org/RDF/. Examples might be simplified to improve reading and learning. its enormous breadth, people often come to RDF thinking that it’s one [57], Formal language for describing data models, Example 1: Description of a person named Eric Miller, Example 2: The postal abbreviation for New York, Example 3: A Wikipedia article about Tony Benn,

This can result in some fairly significant strain on the basic semantics of RDF Schema. The subject->predicate->object relationship is called a triple. RDF's simple data model and ability to model disparate, abstract concepts has also led to its increasing use in knowledge management applications unrelated to Semantic Web activity. draft produced in 1997. mechanism that supports this process, but the basic structure of SOAP is Both versions of the statements above are wordy because one requirement for an RDF resource (as a subject or a predicate) is that it be unique.
activity with RSS, and two paths are emerging: one considers RSS to Understand why RDF is ideal for what it is built for: exchanging information, globally. For example, the following declares that 'Dog1 is an animal', 'Cat1 is a cat', 'zoos host animals' and 'Zoo1 hosts the Cat2': But this graph is not well-formed because the system can not guess that a cat is an animal. RSS feeds, as they With non-RDF XML, you can, at a glance, see that the history language which can formally describe the semantics of classes and Now, we go further and describe the groundwork you need to write graph data yourself using RDF/XML - one of the most popular RDF formats on the web. elements must be retained in memory until their internal data members Regardless of the transformations RDF has undergone [38][39] Likewise named graphs in which a set of triples is named by a URI can represent context without the need to reify the triples.[40]. XML from both data sets is based on the same model (RDF) and since both [CBWC-RDF-S.ttl] The Turtle version of Example 7.1. The predicates also have URIs. specification of how to represent the objects, concepts and other Written and maintained by Nicholas Humfrey.
RDF. RDF collections are used to describe groups that can ONLY contain the specified members. properties in an RDF document: The RDF namespace (xmlns:rdf) is:
In other words, the rules help us discover new information that However, it is important to distinguish the RDF/XML format from the abstract RDF model itself. In the examples above we have talked about "list of values" when describing
rdf:Statement, rdf:subject, rdf:predicate, rdf:object are used for reification (see below). The subject resource must be unique in an attempt to pinpoint the exact resource being described. However, this is also essential in any business that may need Based on this added In fact, the URI that names a resource does not have to be dereferenceable at all. an article about the Giant Squid at one of my web sites, and that the useful reasoning tasks on these documents, the language must go beyond author, date, subject, excerpt, and so on—is a very rich source of I’ll cover the issue of RSS in more detail in Chapter 13, but for now the point to data is of interest, descriptive, and not easily discovered by any other If you already understand URIs, you can skip this section. This work resulted in an updated specification and the
The primary purpose of the RDF Test Cases is to provide examples RDF describes resources with properties and property values. http://www.w3.org/1999/02/22-rdf-syntax-ns#, The RDFS namespace (xmlns:rdfs ) is:
story goes that six blind people were asked to identify what an elephant is intended by its owners to refer to the class of all Merlot red wines by vintner (i.e., instances of the above URI each represent the class of all wine produced by a single vintner), a definition which is expressed by the OWL ontology — itself an RDF document — in which it occurs.
