By Pim Keizer A simple example of some generic sparql queries for use in a  search engine. Search phrase:    “Adidas”  Instance match Select all instances with label "Adidas".   SELECT * WHERE {     ?resource rdfs:label "Adidas" . }   Find synonyms Select all classes that are of the same type. SELECT ?synonyms WHERE {     ?resource rdfs:label "Adidas" .     ?resource rdf:type ?type .     ?synonyms rdf:type ?type . }   Find other instances [...]

The Media Annotations Working Group published an ontology for media resource.   Overview of the Media Annotations Working Goup

Just started a new semantic web project. I will write about this on this website! It is a project about traveling

In the W3C Recommendation of 27 October 2009 the OWL 2 Web Ontology Language is presented. The primer provides an approachable introduction to OWL 2, including orientation for those coming from other disciplines. Visit W3C

RDF is short for Resource Description Framework. RDF is the language for describing resources and contents in the semantic web. In the semantic web RDF is used to describe resources on the web. Resources are addressed by a unique URI. A URI looks like a normal Internet URL. Look at the following fragment of a RDF file: <?xml version="1.0"?> <rdf:RDF     xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"     xmlns:owl="http://www.w3.org/2002/07/owl#"     xmlns:xsd="http://www.w3.org/2001/XMLSchema#"     xmlns="http://example.org/pets#"     xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"   xml:base="http://example.org/pets">   <owl:Class rdf:ID="Goldfish"> [...]

Describing things in a way that computer applications can understand it. The semantic web describes relations between concepts. For example: A isPartOf B B hasType C C isMemberOf D Also properties of concepts can be described: A hasAge X B hasSize X C has Length X Where in this case X could be of type Integer.

The Web Ontology Language (OWL) is a standard for creating web ontologies. It is an official W3C standard. With a well created ontology you can query for data.

"In computer science and information science, an ontology is a formal representation of a set of concepts within a domain and the relationships between those concepts. It is used to reason about the properties of that domain, and may be used to define the domain." (http://en.wikipedia.org/wiki/Ontology_%28information_science%29)

W3Schools has very useful information for the beginner. If you’re not familiar with the concept of OWL, you should start with this website. Many examples. Visit websites
