RDF browser that shapes information
Zitgist is a semantic web query service . They recently released Zitgist RDF browser. This browser presents information of a 'thing' in a format that is easier to browse and understand. The metadata element tag and its value are displayed by the query service. This metadata based database built for Zitgist query service can be used for 'open market' application with a normative metadata.
The difference in the semantic web query service and web 2.0 search engines is that the former reads data from the RDF triples, whereas the latter may be an HTML or XML document. The web 2.0 search engine will generally display the list of URIs for the search query and this URI will display the web page where the search query term may have been used. In the semantic web query engines since data is read from the RDF triples, it is possible to display information in different formats. The search engine will search all RDF triples on the WWW or a local data source and present information contained in the associated triples. The information in these triples may be literal values or other URIs. We already discussed that all elements of a RDF triple are considered as a 'thing' with a URI.
| Example: <thing_URI> property1 value1 <thing_URI> property2 value2 <thing_URI> property3 value3 |
If thing_URI is entered as a query, the result could be either this URI web page or a different web page that displays all the associated properties and objects for this 'thing'. Since the property and objects can be URIs, the web user can traverse the RDF graph of a 'thing' and also reach the web page associated with this URI.
