XML Schema限制了XML文档的结构,但是RDF Schema定义了RDF数据模型中使用的词汇(vocabulary)。 In RDFS we can define the vocabulary, specify which properties apply to which kinds of objects and what values they can take, and describe the relationships between objects. RDFS让语义信息机器可读。 2. RDF中...

RDF is a way to define a triple 'subject','predicate', 'value'. For example, if I want to say, "my name is Pierre" I would write <mail:me@where.com> <foaf:name> "Pierre" See the <foaf:name> ? it is part of the FOAF ontology. An ontology is a formal way to describe ...
The Semantic Web will build on XML's ability to define customized tagging schemes and RDF's flexible approach to representing data. The first level above RDF required for the Semantic Web is an ontology language what can formally describe the meaning of terminology used in Web documents. If mac...
This is a basic primer to RDF, including its common serializations, but there is much more to learn. Upcoming lessons will teach you how to query RDF using SPARQL, and how to define data models in RDF using RDF and OWL.Next Lesson ...
Define a subject to filter: mySubject=" http://ibm.com/ns/netcool-impact/data/SCR_Components#ID"; Retrieve all the statements that containmySubjectfrom the model: allStatements=RDFSelect(rdf,mySubject,null,null); Use theRDFModelfunction to create a new model: ...
An RDF vocabulary is a collection of IRIs intended for use in RDF graphs.For example, the IRIs documented in [RDF11-SCHEMA] are the RDF Schema vocabulary. RDF Schema can itself be used to define and document additional RDF vocabularies. ...
Most XML specifications define data in a tree-like model, such as XUL and XBL. But the RDF Data Model cannot be represented in a true tree-like structure, so the RDF/XML syntax includes properties that allow you to represent the same data in more than one way: elements can appear in...
