Altova SemanticWorks

SemanticWorks is a comprehensive and reliable application that provides users with the ability to edit RDF and OWL files.
Graphically design RDF instance documents, RDFS vocabularies, and OWL ontologies, then output them in either RDF/XML or N-Triples formats.
SemanticWorks makes the job easy with tabs for instances, properties, classes, etc., context-sensitive entry helpers, automatic format checking, and more.
Today, the W3C is looking towards the next evolution in Web technologies: the Semantic Web. In the Semantic Web data itself becomes part of the Web and is able to be processed independently of application, platform, or domain.
Where the current Web is a collection of documents, the Semantic Web is more like a huge database, in which data on Web pages as well as in databases and legacy systems can be searched, processed, and acted on by machines in meaningful ways.
The Semantic Web relies on structured sets of metadata and inference rules that allow it to “understand” the relationship between different data resources.
The technologies that form the basis of the Semantic Web by adding these metadata and inference rules are RDF (Resource Description Framework) and OWL (Web Ontology Language).System requirementsPentium III processor 800 MHz recommended
