    v41 v42  
    3737At a philosophical level, the semantic web enhances science because it forces us to clearly and formally define meanings, intentions and problems. This in turn promotes collaboration, reproducibility and more precise communication. At a technical level, the semantic web makes it easier to get other specialists' data and its computational meaning. Syntax is not enough for this, because syntax can be abused and misinterpreted - true tape safety and end-user usability depends on well-defined semantics. An additional technical benefit is that defining the semantics (i.e. what you mean, what you intend to do), you don't have to hardcode to a particular syntax; hence, web service components become more flexible. 
    3838== Contributing technologies == 
     39The following subsections describe the core technologies that are involved in developing semantic web services (RDF, OWL, SAWSDL). 
    3940=== RDF === 
    4041[http://www.w3.org/RDF/ RDF] assumes that anything in the world can be described in triples, i.e. statements consisting of subject, predicate, object. [http://www.w3.org/TR/rdf-syntax-grammar/ RDF/XML] is just one serialization of the concept of triples (other ways are [http://www.w3.org/DesignIssues/Notation3 N3], [http://www.json.org/ JSON], [http://www.w3.org/TR/rdfa-syntax/ RDFa] etc.). An RDF/XML document imports at least two namespaces: rdf and [http://www.w3.org/TR/rdf-schema/ rdfs].
