Convert the output of xml_to_rdf/3 from library(rdf) into a list of triples of the format described below. The intermediate representation should be regarded a proprietary representation.

rdf(Subject, Predicate, Object).

Where `Subject' is

Atom

The subject is a resource

each(URI)

URI is the URI of an RDF Bag

prefix(Pattern)

Pattern is the prefix of a fully qualified Subject URI

And `Predicate' is

Atom

The predicate is always a resource

And `Object' is

Atom

URI of Object resource

literal(Value)

Literal value (Either a single atom or parsed XML data)

 rdf_triples(+Term, -Triples) is det

 rdf_triples(+Term, -Tridpples, +Tail) is det

Convert an object as parsed by rdf.pl into a list of rdf/3 triples. The identifier of the main object created is returned by rdf_triples/3.

Input is the `content' of the RDF element in the format as generated by load_structure(File, Term, [dialect(xmlns)]). rdf_triples/3 can process both individual descriptions as well as the entire content-list of an RDF element. The first mode is suitable when using library(sgml) in `call-back' mode.

 rdf_start_file(+Options, -Cleanup) is det

Initialise for the translation of a file.

 rdf_end_file(:Cleanup) is det

Cleanup reaching the end of an RDF file.

 anon_prefix(-Prefix) is semidet

If defined, it is the prefix used to generate a blank node.

 rdf_reset_ids is det

Utility predicate to reset the gensym counters for the various generated identifiers. This simplifies debugging and matching output with the stored desired output (see rdf_test.pl).

Re-exported predicates

The following predicates are exported from this file while their implementation is defined in imported modules or non-module files loaded by this module.

 rdf_triples(+Term, -Triples) is det
