Semantic Web Tutorial. C Semantic Web Activity. The Semantic Web is a web of data. There is lots of data we all use every day, and it is not part of the web. I can see my bank statements on the web, and my photographs, and I can see my appointments in a calendar. But can I see my photos in a calendar to see what I was doing when I took them? Can I see bank statement lines in a calendar?
Why not? Because we don't have a web of data. Because data is controlled by applications, and each application keeps it to itself. The Semantic Web is about two things. See also the activity news for an account of recent events, publications, etc. The following groups are part of the Semantic Web Activity. Active Groups Semantic Web Coordination Group The Semantic Web Coordination Group is tasked to provide a forum for managing the interrelationships and interdependencies among groups focusing on standards and technologies that relate to this goals of the Semantic Web Activity. RDFa Working Group RDF Working Group Linked Data Platform Working Group. Linked Data | Strategies for Building Semantic Web Applications. Linked Data uses the web to connect related pieces of information. This information is published on the web in RDF datasets which use either OWL ontologies or RDFS vocabularies to define the types of the individual data elements and the relationships between them.
Through the RDF linkage of related pieces of information in the different datasets Linked Data can be queried like a global database (using SPARQL) and traversed by following the (RDF) links connecting individual data elements. Linked Data (a.k.a. the Web of Data ) is an important goal of the Semantic Web. The web of data is created using HTTP, URIs and RDF and the following design principles: Use URIs as names for things.Use HTTP URIs so that people can look up those names.When someone looks up a URI, provide useful information, using the standards (RDF, SPARQL).Include links to other URIs. so that they can discover more things. The power of Linked Data for is starting to be demonstrated. Additional Information.
