Class RDFDataMgr

  • public class RDFDataMgr
extends java.lang.Object

    General purpose reader framework for RDF (triples and quads) syntaxes.

    • HTTP Content negotiation
    • File type hint by the extension
    • Application language hint

    It also provides a way to lookup names in different locations and to remap URIs to other URIs.

    Extensible - a new syntax can be added to the framework.

    Operations fall into the following categories:

    • read -- Read data from a location into a Model, Dataset, etc. The methods in this class treat all types of Model in the same way. For behavior specific to a subtype of Model, use the methods of that specific class.
    • loadXXX -- Read data and return an in-memory object holding the data.
    • parse -- Read data and send to an StreamRDF
    • open -- Open a typed input stream to the location, using any alternative locations
    • write -- Write Model/Dataset etc
    • create -- Create a reader or writer explicitly

    RDFDataMgr provides single functions for many of the common application patterns. It is built on top of RDFParser for reading and RDFWriter for output. Each of these classes has an associated builder that provides complete control over the parsing process. For example, to translate language tags to lower case on input: 

         RDFParser.create()
         .source("myData.ttl")
         .langTagLowerCase()
         .parse(graph);
    or to have Turtle written with BASE and PREFIX rather than @base and @prefix (both are legal Turtle): 
         RDFWriter.create()
         .set(RIOT.symTurtleDirectiveStyle, "rdf11")
         .source(model)
         .output(System.out);
