This module implements extraction of RDFa triples from parsed XML or
HTML documents. It has two interfaces: read_rdfa/3
to read triples from some input (stream, file, URL) and xml_rdfa/3
to extract triples from an HTML or XML document that is already parsed
with load_html/3 or
load_xml/3.
- [det]read_rdfa(+Input,
-Triples, +Options)
- True when Triples is a list of
rdf(S,P,O)
triples extracted from
Input. Input is either a stream, a file name, a
URL referencing a file name or a URL that is valid for http_open/3. Options
are passed to open/4, http_open/3
and xml_rdfa/3. If no base is
provided in Options, a base is deduced from Input.
- xml_rdfa(+DOM,
-RDF, +Options)
- True when RDF is a list of
rdf(S,P,O) terms
extracted from DOM according to the RDFa specification. Options
processed:
- base(+BaseURI)
- URI to use for” . Normally set to the document URI.
- anon_prefix(+AnnonPrefix)
- Prefix for blank nodes.
- lang(+Lang)

- [multifile]rdf_db:rdf_load_stream(+Format,
+Stream, :Options)

library(semweb/rdfa) as loader for HTML RDFa
files.
- To be done
- Which options need to be forwarded to read_rdfa/3?
