Deserialize JSON-LD to RDF Algorithm step 1.3.2.5.3 says:
Append a triple composed of subject
, property
, and the result of using the Object to RDF Conversion algorithm passing item
and list triples
to triples
, unless the result is null
, indicating a non-well-formed resource that has to be ignored.
The use of "append" language in reference to triples
is confusing here, as triples
is an RdfGraph
which can have triples added to it with the add
method (which is what step 1.3.2.5.4 does).
