Conversion to RDF

Received data are immediately converted into RDF.

Only SituationRecord alements are converted and from those only the ones, which are classified as Safety Related Traffic Information.

Sample RDF representation in turtle format may look like this:

@prefix datex: <http://cef.uv.es/lodtran18#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
