RDF/JS Wrapper

An RDF/JS object mapping library.

Background

RDF/JS Wrapper facilitates object-oriented programming over RDF (see RDF, Knowledge Graph).

RDF/JS Wrapper uses the interfaces described in the RDF/JS specifications.

Practically, to map RDF to objects, you need to:

1. Write a class or use an existing class that extends TermWrapper
2. Each class needs a Term, a Dataset, and a DataFactory to be instantiated
3. Each class property will have an associated RDF Property (a string, generally a URL, that is defined by an ontology/vocabulary)
4. Each class property depending on its type can have:
   1. a corresponding ValueMapping to get values, that is translating RDF Terms to JavaScript primitive values (string, number, boolean...)
   2. a corresponding TermMapping to set values, that is translating Javascript primitive values to RDF Terms
   3. a corresponding ValueMapping and TermMapping for sets of primitive values
   4. a corresponding TermWrapper for properties returning a class
   5. two corresponding TermWrappers (generally the same) for sets of classes
5. Each class mutates the underlying Dataset that is passed to it for instantiation
