- If provided local identifiers and identifier-references are globalised
using this URI. If omited or the atom
, local identifiers are not tagged.
- If Mode is
share(default), blank-node properties (i.e. complex properties without identifier) are reused if they result in exactly the same triple-set. Two descriptions are shared if their intermediate description is the same. This means they should produce the same set of triples in the same order. The value
nosharecreates a new resource for each blank node.
- If Boolean is
rdf:aboutEachinto a set of triples. By default the parser generates
rdf(each(Container), Predicate, Subject).
- Define the initial language (i.e. pretend there is an
xml:langdeclaration in an enclosing element).
xml:langdeclarations in the document are ignored. This is mostly for compatibility with older versions of this library that did not support language identifiers.
- If the parser finds a literal with the
rdf:datatype=Type attribute, call
ConvertPred(+Type, +Content, -Literal). Content is the XML element contentas returned by the XML parser (a list). The predicate must unify Literal with a Prolog representation of Content according to Type or throw an exception if the conversion cannot be made.
This option servers two purposes. First of all it can be used to ignore type declarations for backward compatibility of this library. Second it can be used to convert typed literals to a meaningful Prolog representation. E.g. convert’42' to the Prolog integer 42 if the type is
xsd:intor a related type.
- Unify List with a list of NS=URL for
xmlns:NS=URL declaration found in the source.
- entity(+Name, +Value)
- Overrule entity declaration in file. As it is common practice to declare namespaces using entities in RDF/XML, this option allows for changing the namespace without changing the file. Multiple of these options are allowed.
The Triples list is a list of
Predicate, Object) triples. Subject is either a plain
resource (an atom), or one of the terms
with the obvious meaning. Predicate is either a plain atom
for explicitely non-qualified names or a term
NameSpace:Name. If NameSpace is
the defined RDF name space it is returned as the atom
Finally, Object is a URI, a Predicate or a term of
literal(Value) for literal values. Value
is either a plain atom or a parsed XML term (list of atoms and
