What is Semantic Web programming?
The term “Semantic Web” refers to W3C’s vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS.
Why Semantic Web is designed using layered approach?
A Layered Architecture To achieve compatibility the Semantic Web uses vocabularies, taxonomies and ontologies. Which contain a set of defined terms and each is critical to the ability to express the meaning of data. A combination of a schema language and an ontology language provide these capabilities.
What are the components of the lower layer of the Semantic Web architecture?
The bottom layers contain technologies that are well known from hypertext web and that without change provide basis for the semantic web. Internationalized Resource Identifier (IRI), generalization of URI, provides means for uniquely identifying semantic web resources.
Why are layers important in the Semantic Web?
Each layer that is added to the Semantic Architecture should follow two principles: Adding layers in this manner will give the technology interoperability. To achieve compatibility the Semantic Web uses vocabularies, taxonomies and ontologies. Which contain a set of defined terms and each is critical to the ability to express the meaning of data.
Which is an example of the Semantic Web stack?
The Semantic Web Stack is an illustration of the hierarchy of languages, where each layer exploits and uses capabilities of the layers below. It shows how technologies that are standardized for Semantic Web are organized to make the Semantic Web possible.
How is the development of the Semantic Web?
The development of the Semantic Web proceeds in layers. One above another. Allowing for a more standardised way of developing. As it is being built on existing technology it allows developers to roll out parts of technology and implementing them. Without realising the full capabilities of the Semantic Web.
How is XML used in the Semantic Web?
Semantic Web should also help to bridge documents in different human languages, so it should be able to represent them. XML is a markup language that enables creation of documents composed of structured data. Semantic web gives meaning (semantics) to structured data.
